THE OFFERING

This Prospectus covers the resale by Selling Securityholders named on page 43 of (1) (a) up to 613,814 Units, each Unit consisting of (i) eight shares of common stock, (ii) eight warrants to purchase one share of common stock at $1.00 per share (the “$1.00 Unit Warrants”), (iii) two warrants to purchase one share of common stock at $1.25 per share (the “$1.25 Unit Warrants”) and (iv) two warrants to purchase one share of common stock at $1.63 per share (the “$1.63 Unit Warrants”, and collectively with the $1.00 Unit Warrants and the $1.25 Unit Warrants, the “Unit Warrants”), (b) up to 7,365,782 Unit Warrants, included in the Units, (c) up to 4,910,522 shares of common stock included in the Units and (d) up to 7,365,782 shares of common stock issuable upon the exercise of the Unit Warrants and (2) up to 1,187,500 shares of common stock issuable upon conversion of the $950,000 5% convertible secured note (the “Convertible Note”).

The manner in which the securities offered under this Prospectus will be sold from time to time by the Selling Securityholders is discussed under the caption “Plan of Distribution” beginning on page 54.

In connection with the sale of the Units in an April 30, 2007 private placement, Lightspace paid Griffin Securities, Inc. (“Griffin”), the financial advisor for the private placement, a fee in the amount of $187,575 and issued to Griffin Unit purchase warrants (the “Griffin Warrants”) exercisable for 58,617 Units, in the same form sold in the private placement and described above, at an exercise price of $6.40 per Unit.

The Selling Securityholders include: (a) certain investors who purchased Units in our private placements completed on April 30, 2007 and May 3, 2006, (b) the holder of our Convertible Note, which is convertible into up to 1,187,500 shares of common stock and (c) the holders of the Griffin Warrants, exercisable to purchase up to 58,617 Units.

Accordingly, this Prospectus covers:

-	the resale by Selling Securityholders of Units and Unit Warrants issued in the April 30, 2007 and May 3, 2006 private private placements;

·	the resale by Selling Securityholders of shares of common stock included in the Units;

·	the resale by Selling Securityholders of shares of common stock issuable upon exercise of certain Unit Warrants issued in the April 30, 2007 and May 3, 2006 private placements; and

·	the resale by a Selling Securityholder of common stock issuable upon conversion of the Convertible Note; and.

·	the resale by Selling Securityholders of Units and securities underlying such Units issuable upon exercise of the Griffin Warrants.

We are not selling any Units, Unit Warrants or certain of the shares of common stock under this Prospectus and will not receive any of the proceeds from the sale thereof by the Selling Securityholders. However, we will receive the exercise price of the Units issuable if the Griffin Warrants are exercised and common stock issuable if the Unit Warrants are exercised for cash by the Selling Securityholders, the proceeds of which, if any, will fund anticipated operating losses and be allocated to working capital and general corporate purposes.

RISK FACTORS

The purchase of Units, shares of our common stock and Unit Warrants involves a high degree of risk. In addition to the other information contained elsewhere in this Prospectus, you should carefully consider the following factors when evaluating an investment in our securities. If any of the adverse events described below actually occur, our business, financial condition and operating results could be materially adversely affected and you may lose part or all of the value of your investment. If you choose to invest in our securities, you should be able to bear a complete loss of your investment.

Because we have a limited operating history, you have a limited basis on which to evaluate our ability to achieve our business objectives.

We have only recently commenced operations. We have only developed and marketed the Lightspace system since 2004. As a result, we have only a limited operating history upon which you can base your evaluation of our prospects and the potential value of our Units, common stock and Unit Warrants. We are confronted with the risks inherent in a start-up company, including difficulties and delays in connection with the production and sales of our Lightspace systems, operational difficulties and our potential under-estimation of production and administrative costs. If we cannot successfully manage our business and growth, we may not be able to generate future profits and may not be able to support our operations.

We are in the early stages of our development, have yet to achieve net earnings since inception and may not generate sufficient revenues to stay in business.

Lightspace has only recently commenced operations and has to date incurred net losses. There can be no assurance that we will achieve or sustain profitability in the future. The success of our business will depend on our ability to introduce and sell our systems to customers, develop new product extensions and applications and raise additional capital for operations, future expanded marketing and further product development. You should consider the costs and difficulties frequently encountered by companies in their early stages of launching a product and establishing a market presence. No assurance can be given that we will generate sufficient revenues to stay in business on achieve profitability. Accordingly, purchasers of Units may lose their entire investment.

Our products are complex and could have unknown defects or errors, which may give rise to claims against us, diminish our brand or divert our resources from other purposes.

Despite testing, our new or existing products have contained defects and errors and may in the future contain defects, errors or performance problems when first introduced, when new versions or enhancements are released, or even after these products have been used by our customers for a period of time. These problems could result in expensive and time-consuming design modifications or warranty charges, delays in the introduction of new products or enhancements, significant increases in our service and maintenance costs, exposure to liability for damages, damaged customer relationships and harm to our reputation. Any of these problems could materially harm our results of operations and ability to achieve market acceptance. In addition, increased development and warranty costs could be substantial and could adversely affect our operating margins.

We may need additional capital, which may not be available on acceptable terms, to fund our growth or sustain our business.

We anticipate that the net proceeds of the April 30, 2007 private placement (and the proceeds, if any; from the exercise of Unit Warrants under this Prospectus), together with anticipated revenues from sales of our products, will be adequate to satisfy our capital requirements for the next 12 months. However, we may require additional capital within such period to support our growth and cover operational expenses as we expand our marketing and product development. Our future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our marketing and sales activities, the timing and extent of spending to support product development efforts, the timing of introductions of new products and enhancements to existing products, the acquisition of new capabilities or technologies, and the continuing market acceptance of our products and services. To the extent that existing cash, cash equivalents, cash from operations and cash from short-term borrowing are insufficient to fund our future activities, we may need to raise additional funds through public or private equity or debt financing. Although we are currently not a party to any agreement or letter of intent with respect to potential investments in, or acquisitions of, businesses, services or technologies, we may enter into these types of arrangements in the future, which could also require us to seek additional equity or debt financing. Additional funds may not be available on terms favorable to us or at all. If we are unable to obtain additional financing on reasonable terms, we may not have sufficient capital to operate our business as planned.

Furthermore, if we are required to refund the price paid by the investors in our unregistered April 2007 placement, then our current resources would be insufficient to fund operations. If we are unable to obtain additional capital when needed, we may not be able to achieve the objectives of our current business strategy, which could force us to delay, curtail or eliminate and product and service development programs, which could materially adversely affect our business.

If we fail to adequately protect our intellectual property and proprietary technology, our ability to produce and market our products may be impaired.

Our success and ability to compete will largely depend upon our ability to protect our proprietary technology, which includes several components of our products. We rely primarily on patent, copyright, trade secret and trademark laws to protect our technology. Lightspace generally enters into confidentiality and invention assignment agreements with our employees, consultants and vendors and generally seeks to control access to our proprietary information. We have applied for patents in the United States and certain other countries for protection of our core technology. Our ability to compete effectively, if at all, with other companies may be materially dependent on such know-how as we develop and upon the issuance of future patents. We cannot assure you that patents will be issued or that, if none are issued, there will be no material adverse effect on our ability to market our products or license our technology. We cannot assure you as to the scope of any patents that may be issued or that claims related thereto would not be asserted by other parties. There can be no assurance that there are no adversely held United States or foreign patents or other forms of proprietary protection that could successfully be asserted against those held by Lightspace.

We cannot assure you that the validity of our patents, if issued, will be sustained if judicially tested, that our products will not infringe upon patents owned by others or that competitors with substantially greater financial resources will not develop similar or functionally-similar products outside the protection of any patents that might be granted to Lightspace. A third party could also assert claims against us, our customers or vendors that our technology infringes the third party’s proprietary rights.

Infringement claims asserted against us or our vendors may have a material adverse effect on our business, results of operations or financial condition. We or our vendors may not be able to withstand such claims. Resolution of any claims, with or without merit, could be time-consuming and expensive, and could divert our management’s attention away from the execution of our business plan. Moreover, any settlement or adverse judgment resulting from the claim could require us to pay substantial amounts or obtain a license to continue to use the technology that is the subject of the claim, or otherwise restrict or prohibit our use of the technology. There can be no assurance that we would be able to obtain a license from the third party asserting the claim on commercially reasonable terms, if at all, that we would be able to develop alternative technology on a timely basis, if at all, or that we would be able to obtain a license to use a suitable alternative technology to permit us to continue offering, and our customers to continue using, our affected product. In addition, we may be required to indemnify our vendors and other partners for third party intellectual property infringement claims, which would increase the cost to us of an adverse ruling in such a claim. An adverse determination could also prevent us from offering our products to others.

The market for our products is uncertain and sales of our Lightspace systems may not generate sufficient revenues to meet our operating expenses.

The business of Lightspace, marketing unique interactive tiles, must be considered a novel industry without substantial precedent or assurance of commercial success. We are introducing our Lightspace systems as new products to customer markets unfamiliar with their use and benefits. Actual demand for our product may be less than we anticipate. If there is an insufficient market for our products, or if our products fail to generate widespread acceptance within the market, our future sales may fail to produce revenues sufficient to meet our operating expenses. If this occurs, our business may fail and the purchasers of Units may lose their entire investment.

Our revenues may experience severe fluctuations, which could cause our business to suffer or fail.

Our operating results have fluctuated in the past and are likely to do so in the future. Our revenues from the sale of our products and services are not predictable with any significant degree of certainty. The length of our sales cycles, which may vary from customer to customer, may last for months, while our short-term expense levels are relatively fixed and based on our expectations for future revenues. Our inability to adequately reduce short-term expenses or to predict our future revenues may adversely affect our business, operating results and financial condition.

We may not be able to compete against existing and potential competitors in the markets we serve.

Our competitors may be able to respond more quickly to new or emerging technologies or changes in customer requirements than we can. In addition, current and potential competitors may have greater name recognition and more extensive customer bases. Increased competition could result in price reductions, fewer customer orders and reduced margins.

If we are unable to improve the effectiveness and breadth of our sales and research and development organizations, our future revenue may be adversely affected.

We will need to improve the effectiveness and breadth of our sales operations in order to increase market awareness and sales of our products. Competition for qualified sales personnel is intense, and we might not be able to hire the kind and number of sales personnel we are targeting. In addition, we will need to effectively train and educate our sales force if we are going to be successful in selling our Lightspace systems. Likewise, our efforts to improve and refine our Lightspace systems require highly skilled engineers and programmers. Competition for professionals capable of expanding our research and development organization is intense due to the limited number of people available with the necessary technical skills. If we are unable to identify, hire or retain qualified sales marketing and technical personnel, our ability to achieve future revenue may be adversely affected.

Our efforts to sell our products internationally may be unsuccessful and result in losses.

We have sold Lightspace systems to a small number of customers in Asia, Australia, Canada, Central and South America, Europe, Japan, Korea and Middle East. Although we intend to expand our international selling efforts, we have limited experience marketing and distributing our products internationally. In addition, other inherent risks may apply to international markets, including:

the impact of recessions in economies outside the United States;

greater difficulty in accounts receivable collections and longer collection periods;

potentially adverse tax consequences;

greater difficulty in protecting our intellectual property;

fluctuations in exchange rates; and

political and economic instability.

The inability to integrate our business in international jurisdictions may adversely affect our future operations.

Our marketing strategies may not be successful, which would adversely affect our future revenues and profitability.

Our revenues and profitability depend on the successful marketing of our Lightspace systems and the development of distribution channels in the United States and internationally. We cannot assure you that customers will be interested in purchasing our products. We initially plan to use direct marketing to sell our products via trade shows, magazine and newspaper advertising and the Internet. If our marketing strategies fail to attract customers or develop adequate sales channels, our product sales will not produce future revenues sufficient to meet our operating expenses or fund our future operations. If this occurs, our business may fail and purchasers of Units may lose their entire investment.

Failures or delays in introducing new technologies or products could negatively impact our revenues.

The potential markets and uses for our Lightspace systems remain uncertain. The introduction of products involving new technologies could render our products obsolete. Our future success and revenue growth will depend on our ability to develop and introduce a variety of new products and product enhancements to address the needs of our customers. We may experience delays in developing our Lightspace systems in the future. Material delays in introducing new products or product enhancements may cause customers to forgo purchases of our products or to purchase those of our competitors.

Our products may not always be compatible with third-party technologies, which could adversely affect our business.

Our products are designed to interact and be compatible with a range of third-party hardware and software technologies used by our customers. The future design and development plans of such third parties may not be in line with out future product development. We may also rely on third parties to license or otherwise provide us with access to these technologies so that we may test and develop compatible products. Third parties may refuse or be otherwise unable to provide us with the necessary access to their technology. If our products cease to be compatible with certain third-party technology, our business and operating results may be materially adversely affected.

We depend on third party suppliers and manufacturers, and our business would be harmed if these parties fail to meet our requirements.

We rely on a small number of critical third party suppliers and third party manufacturers for key components, many of which are custom-built to our specifications. We outsource the manufacture of all commodity components that are made with materials and components procured from third party suppliers. If we fail to develop or maintain relationships with these or other suppliers, or if these suppliers are unable to provide components as we require, we may be unable to manufacture our products or our products may be available only at a higher cost or after a long delay, which could prevent us from delivering products to customers within required timeframes. In addition, our manufacturers may fail to produce the products for our Lightspace systems to our specifications, in sufficient quantities to meet our needs or in a workmanlike manner and may not deliver the products on a timely basis. Any change in manufacturers could disrupt our business due to delays in finding a new manufacturer, providing specifications and testing initial production. As a result, we may experience order cancellation and loss of future revenues.

We have experienced turnover among key officers and employees, and any inability to attract qualified successors in the future could harm our business and prospects.

Our employment relationships are generally at will. Andrew Kennedy Lang, our former Chief Executive Officer, recently resigned from all positions with Lightspace effective March 31, 2006. Our former Chief Financial Officer resigned from Lightspace effective February 15, 2007 and was replaced on April 30, 2007. We also recently lost senior engineering personnel. We are in the process of interviewing candidates for these positions. We can make no assurances that additional key employees will not leave us in the future. If any more of our key employees, including any of our officers, were to leave us, we could face substantial difficulty in hiring qualified successors and could experience a loss in productivity while any such successor obtains the necessary training and experience. We do not have key person life insurance covering any of our employees.

Lightspace management has limited experience in the management of a public entity.

The management of Lightspace consists of individuals who have limited experience in the management of a public company. Failure to properly comply with the obligations required of a public company could result in shareholder suits, substantial costs and a diversion of management’s attention and resources.

A trading market for our Units, common stock and Unit Warrants may not develop or be sustained, which may limit your ability to resell our securities.

There is a limited trading market for our securities at this time. Our securities are quoted on the OTC Bulletin Board. If an active public trading market does not develop and continue, you may have limited liquidity and may be forced to hold your Units, common stock and Unit Warrants for an indefinite period of time.

The market for our common stock and Unit Warrants may be limited, and our Stockholders may have difficulty reselling their shares and Unit Warrants when desired or at attractive prices.

Even if a trading market develops, our common stock and Unit Warrants may trade in low volumes and at low prices. Some investors view low-priced stocks as unduly speculative and therefore not appropriate candidates for investment. Many institutional investors have internal policies prohibiting the purchase or maintenance of positions in low-priced stocks. This has the effect of limiting the pool of potential purchases of our securities at present price levels. Stockholders may find greater percentage spreads between bid and asked prices, and more difficulty in completing transactions and higher transaction costs when buying or selling our securities than they would if our common stock were listed on a major stock exchange, such as The New York Stock Exchange or The NASDAQ National Market.

Additionally, the market prices for securities of software and technology companies have been volatile throughout our existence. Historical trading characteristics for public companies in this industry include limited market support, low trading volume, and wide spreads (on a percentage basis) between the bid and ask prices. Announcements regarding product developments, technological advances, significant customer orders, and financial results may significantly influence per share prices.

We do not intend to register our securities under Section 12(g) of the Exchange Act, which may limit your access to information about us.

We do not intend to register our securities under Section 12(g) of the Exchange Act unless and until we are required based on having at least 500 Stockholders of record and a certain amount of assets. While we will be subject to the periodic reporting requirements of Section 15(d) of the Exchange Act, we will not be subject to certain other provisions of the Exchange Act, including those related to proxy and information statements, insider reporting and short-swing profit liability, reporting by certain beneficial owners of our equity securities, and rules relating to tender offers. Certain provisions of the Sarbanes-Oxley Act also will not apply to us until we are registered under Section 12. As a result, you may not have access to certain information that is otherwise generally available to holders of publicly traded securities.

We must comply with new regulatory requirements regarding internal control over financial reporting and corporate governance, which will cause us to incur increased costs, and our failure to comply with these requirements, could cause our stock price to decline.

Commencing in 2008, section 404 of the Sarbanes-Oxley Act of 2002 requires that we annually evaluate and report in Form 10-K on our systems of internal controls and that our independent registered public accounting firm must report on our evaluation of those controls. We have had material weaknesses in our internal controls in the past. We cannot assure you that there will not in the future be material weaknesses in our internal controls that would be required to be reported in future Annual Reports. A negative reaction by the equity markets to the reporting of a material weakness could cause our stock price to decline.

We are also spending an increased amount of management time and focus as well as external resources to comply with changing laws, regulations and standards relating to corporate governance and public disclosure. This has resulted in additional accounting and legal expenses. These additional expenses could adversely affect our operating results and the market price of our stock could suffer as a result.

Our common stock is subject to the Securities and Exchange Commission’s “penny stock” regulations, which limit the liquidity of common stock held by our Stockholders.

Based on the anticipated trading price, our common stock and Unit Warrants are considered “penny stock” for purposes of federal securities laws, and therefore subject to regulations which affect the ability of broker-dealers to sell our securities. Broker-dealers who recommend a “penny stock” to persons (other than established customers and accredited investors) must make a special written suitability determination and receive the purchaser’s written agreement to a transaction prior to sale.

As long as the penny stock regulations apply to our common stock and Unit Warrants, it may be difficult to trade such securities because compliance with the regulations can delay and/or preclude certain trading transactions. Broker-dealers may be discouraged from effecting transactions in our securities because of the sales practice and disclosure requirements for penny stock. This could adversely affect the liquidity and/or price of our common stock and Unit Warrants, and impede the sale of our common stock and Unit Warrants in the secondary market.

Unit Warrants may have limited value unless the price of our common stock equals or exceeds the exercise price of the Unit Warrants at the time of exercise.

The price of our common stock may not meet or exceed the exercise price of the Unit Warrants during the Warrant exercise period. If this happens, the value of common stock which you purchase by exercising your warrants may be significantly less than the exercise price which you must pay. If you choose not to exercise your Unit Warrants during the exercise period, your Unit Warrants will expire. As a result your Unit Warrants may become worthless.

The Unit Warrants are exercisable during periods that continue until April 30, 2012. If the current registration statement does not continue in effect, you may not be able to exercise your Unit Warrants or resell the shares of common stock issuable upon exercise thereof.

The Unit Warrants may be exercised at any time during periods that continue until April 30, 2012. We plan to keep our registration statement current so long as any of the Unit Warrants are outstanding. However, if a current registration statement is not in effect, you may not be able to exercise your Unit Warrants (unless you have an exemption from registration) or resell the shares of common stock issuable upon exercise thereof. If at their expiration date the Unit Warrants are not currently exercisable, the expiration date will be extended until 30 days following notice to the holders of the Unit Warrants that the Unit Warrants are again exercisable. Nevertheless, there is a possibility that you will never be able to exercise the Unit Warrants, and that you will never receive shares of our common stock. This potential inability to exercise the Unit Warrants may have an adverse effect on demand for the Unit Warrants and the prices that can be obtained from reselling them.

If an exemption from registration on which we have relied on for any of our past offerings of securities were later challenged legally, we may have to expend time and money defending them or risk paying expenses for defense or rescission.

We have previously offered our securities in private transactions in reliance on exemptions from registration under the Securities Act of 1933, as amended (the “Securities Act”), and state securities laws. In the future, if the basis of an exemption were challenged, we risk potential claims which could require rescission of those transactions with return of funds and interest to the investors. Such claims could be expensive and time consuming to defend and if we are unsuccessful could have a material adverse effect on our business.

There may be substantial sales of our common stock by Selling Securityholders which could cause the price of our stock to fall.

Future sales of substantial amounts of our common stock in the public market could cause the market price of our common stock to decline. We have 15,282,495 shares of common stock outstanding. 5,793,111 shares of common stock and 6,187,789 Exchange and Unit Warrants are subject to a lock-up period ending October 4, 2007, and will be available for sale at various times thereafter. The sales of common stock or Unit Warrants by these Selling Securityholders may depress any trading market for our securities.

Our certificate of incorporation authorizes us to issue additional shares of stock, which could dilute your ownership interest and influence in Lightspace.

We are authorized to issue up to 75,000,000 shares of common stock, which may be issued by our board of directors for such consideration as they may deem sufficient without seeking shareholder approval. The issuance of additional shares of common stock in the future will reduce the proportionate ownership and voting power of current Stockholders.

Outstanding warrants and options, and additional future obligations to issue our securities to various parties, may dilute the value of your investment and may adversely affect our ability to raise additional capital.

As of June 20, 2007, we had committed to issue up to 26,540,390 additional shares of common stock under the terms of Unit Warrants, other warrants, options and the Convertible Note, that can be exercised or converted at exercise prices ranging from $0.80 to $7.50 per share.

We have historically issued shares of our common stock or granted stock options to employees, consultants and vendors as a means to conserve cash, and we may continue to grant additional shares of stock and issue stock options in the future. As of June 20, 2007, we had outstanding options to purchase 1,718,685 shares of our common stock to a director, officers and employees under our 2005 and 2006 Stock Incentive Plans. Under our 2006 Stock Incentive Plan, we have the authority to grant an additional 399,937 common stock options to directors, officers, employees and consultants. The 2005 Stock Incentive Plan and the 2006 Stock Incentive Plan are described beginning on page F-19 of this Prospectus. We also have outstanding a $950,000 principal amount Convertible Note, convertible into 1,187,500 shares of common stock.

For the length of time these warrants, options and note are outstanding, the holders will have an opportunity to profit from a rise in the market price of our common stock without assuming the risks of ownership. This may adversely affect the terms upon which we can obtain additional capital. The holders of such derivative securities would likely exercise or convert them at a time when we would be able to obtain equity capital on terms more favorable than the exercise or conversion prices provided by the note, warrants or options.

We have not paid dividends on our common stock in the past and do not expect to do so in the future.

We cannot assure you that our operations will result in sufficient revenues to enable us to operate at profitable levels or to generate positive cash flow sufficient to pay dividends. We have never paid dividends on our common stock in the past and do not expect to do so in the foreseeable future.

Our management will have broad discretion over the use of proceeds, if any, from exercise of Unit Warrants or Griffin Warrants, and may invest or spend the proceeds in ways with which you disagree.

We will have broad discretion as to how the net proceeds, if any, from the exercise of Unit Warrants or Griffin Warrants will be used. While we anticipate that we will use the net proceeds from this Offering generally as set forth under “Use of Proceeds” beginning on page 12, you will be relying generally on the judgment of our board of directors and management regarding the application of the proceeds. Management’s failure to apply these funds effectively could have an adverse effect on our ability to execute our business plan.

A majority of our common stock and warrants will be held by a small number of parties. As a result, our other Selling Securityholders may be unable to affect the outcome of any stockholder voting.

A majority of the outstanding shares of our common stock is beneficially owned by a small number of persons who may be able to control the outcome of any stockholder vote. Such power could have the effect of delaying, deterring or preventing a change of control, business combination or other transaction that might otherwise be beneficial to our Selling Securityholders and warrantholders. These factors could be viewed adversely by the market and could depress the prevailing market price for our common stock and warrants. Furthermore, sales of substantial amounts of our common stock or warrants, or the perception that these sales might occur, may also depress prevailing market prices of our common stock and warrants.

Changes in the accounting treatment of stock options will adversely affect our results of operations.

Statement of Financial Accounting Standards No. 123(R), Share-Based Payment, issued in 2004, addresses accounting for stock-based compensation arrangements, including stock options and shares issued to employees and directors under various stock-based compensation arrangements. This statement requires that we use the fair value method, rather than the intrinsic-value method, to determine compensation expense for all stock-based arrangements. Under the fair value method, stock-based compensation expense is determined at the measurement date, which is generally the date of grant, as the aggregate amount by which the expected future value of the equity security at the date of acquisition exceeds the exercise price to be paid. The resulting compensation expense, if any, is recognized for financial reporting over the term of vesting or performance. This statement was first effective for us on January 1, 2006 for all prospective stock option and share grants of stock-based compensation awards and modifications to all prior grants, and will have the affect of increasing our compensation costs recognized in operations from historical levels for all stock-based compensation awards and modifications of prior awards granted.

PENNY STOCK CONSIDERATIONS

Our common stock is currently considered penny stock. Broker-dealer practices in connection with transactions in “penny stocks” are regulated by certain penny stock rules adopted by the Securities and Exchange Commission (the “Commission”). Penny stocks generally are equity securities with a price of less than $5.00 (other than securities registered on certain national securities exchanges or quoted on the NASDAQ system). Penny stock rules require a broker-dealer, prior to a transaction in a penny stock not otherwise exempt from the rules, to deliver a standardized risk disclosure document that provides information about penny stocks and the risks in the penny stock market. The broker-dealer also must provide the customer with current bid and offer quotations for the penny stock, the compensation of the broker-dealer and its salesperson in the transaction, and monthly account statements showing the market value of each penny stock held in the customer’s account. The broker-dealer must also make a special written determination that the penny stock is a suitable investment for the purchaser and receive the purchaser’s written agreement to the transaction. These requirements may have the effect of reducing the level of trading activity, if any, in the secondary market for a security that becomes subject to the penny stock rules.

DETERMINATION OF OFFERING PRICE

The Units, Unit Warrants and shares of common stock offered under this Prospectus will be sold from time to time by the Securityholders at prices then currently prevailing in the market or at negotiated prices. See the discussion under the caption “Plan of Distribution” beginning on page 54. There is no fixed or currently determinable price at which any of the Units, Unit Warrants or shares of common stock will be offered or sold.

USE OF PROCEEDS

We will not receive any proceeds from the sale of the securities by the Selling Securityholders. All proceeds from the sale of the securities offered hereby will be for the account of the Selling Securityholders, as described below in the sections titled “Selling Securityholders” and “Plan of Distribution.” However, we received $4,698,872 from the Unit private offerings which we completed on May 3, 2006 and April 30, 2007 which includes 4,441,586 shares of common stock covered by this Prospectus, and we may receive up to $375,148 upon exercise of the Griffin Warrants and additional proceeds from exercise of the Unit Warrants, the underlying shares of which are included in the registration statement of which this Prospectus is a part, if the Warrants are exercised by the Selling Securityholders. We currently anticipate that all of the proceeds from the exercise of Unit Warrants from the private offerings and proceeds from the exercise of the Griffin Warrants and Unit Warrants, if any, will fund anticipated operating losses and be allocated to working capital and general corporate purposes. We will invest such proceeds in short-term interest-bearing securities or money market funds pending use. Management reserves the right to allocate the proceeds differently than as set forth above relevant to the actual needs of the Company over time including larger allocations to general corporate purposes, and working capital requirements.

With the exception of any brokerage fees and commissions which are the obligation of the Selling Securityholders, we are responsible for the fees, costs and expenses of this offering which are estimated to be $83,425 inclusive of our legal and accounting fees, printing costs and filing and other miscellaneous fees and expenses.

Lightspace is obligated to use its best efforts to repay an outstanding obligation to Immersive Promotions, an affiliate of our former CEO. We do not interpret this obligation as requiring repayment under circumstances that could leave us with insufficient capital to meet our long-term requirements. We do not intend to repay the obligation to Immersive Promotions until we generate sufficient revenues from which to make such payment. The payment to Immersive Promotions will not be made from the proceeds of the Offering. See “Certain Relationships and Related Transactions—Immersive Promotions” beginning on page 46.

Market for Common Equity and Related Stockholder Matters

Shortly after the Closing of our initial public offering on November 2, 2006, our common stock, units, $1.00 warrants, $1.25 warrants and $1.63 warrants were approved for trading on the OTC Bulletin Board (www.otcbb.com). Our equity securities trade under the following OTC Bulletin Board symbols: common stock, “LGTS”; units, “LGTSU”; $1.00 warrants, “LGTSW”; $1.25 warrants, “LGTSZ”; and $1.63 warrants, “LGTSL”.

Continental Stock Transfer & Trust Company, 17 Battery Place, New York, New York 10004, is the transfer agent and registrar for our equity securities. The telephone number of our representative at Continental Stock Transfer & Trust Company is 212-845-3204.

Since the date of our initial public offering on November 2, 2006, through December 31, 2006, only our units have traded on the OTC Bulletin Board. Since January 1, 2007 through June 15, 2007, only our common stock and units have traded on the OTC Bulletin Board. The following table sets forth, for the periods indicated, the range of the high and low trade prices for our common stock and units.

Year ended December 31, 2007	Equity Security		High		Low

Quarter ended December 31, 2006		Unit	$	8.00	$	6.40

As of June 15, 2007, our common stock and units were held by approximately 85 shareholders of record.

DIVIDEND POLICY

We have never declared or paid any cash dividends on our common stock. We currently intend to retain any future earnings to finance the growth and development of our business and therefore do not anticipate paying any cash dividends in the foreseeable future. Our board of directors will determine any future payment of cash dividends depending on our financial condition, results of operations, capital requirements, general business condition and other relevant factors. If we issue preferred shares, although currently not anticipated, no dividends may be paid on our outstanding common stock until all dividends then due on our outstanding preferred stock have been paid.

HISTORICAL AND PRO FORMA FINANCIAL STATEMENTS

The historical financial statements of operations and financial position of Lightspace and the unaudited pro forma statements of operations and financial position have been derived from the historical financial statements of Lightspace as of December 31, 2006 and March 31, 2007 and for the year and the quarter then ended, respectively. The unaudited pro forma statements of operations for the year ended December 31, 2006 and the quarter ended March 31, 2007 have been adjusted to give effect to the April 30, 2007 acquisition of the emagipix technology and the April 30, 2007 private placement of 586,173 equity units, as if such transactions had occurred as of January 1, 2006. The unaudited pro forma statement of financial position at March 31, 2007 has been adjusted to give effect to these two transactions, as if they had occurred as of March 31, 2007. The unaudited pro forma statements of operations are presented for informational purposes only and do not purport to be representative of the results of operations that actually would have occurred if the transactions had occurred on January 1, 2006. These historical and unaudited pro forma statements should be read in conjunction with the notes thereto and the audited historical financial statements as of December 31, 2006 and the unaudited financial statements as of March 31, 2007 and notes thereto, beginning on page F-1 of this Prospectus.

(1) Private Placement of Equity Securities

On April 30, 2007 Lightspace closed a private placement of its equity units. We sold 586,173 equity units at the offering price of $6.40 per unit, resulting in aggregate proceeds to us of $3,751,507. After estimated expenses of the offering of $311,507, the net proceeds were approximately $3,440,000. Each equity unit consists of: (1) eight shares of common stock; (2) eight warrants to purchase a total of eight shares of common stock at an exercise price of $1.00 per warrant; (3) two warrants to purchase a total of two shares of common stock at an exercise price of $1.25 per warrant; and (4) two warrants to purchase a total of two shares of common stock at an exercise price of $1.63 per warrant. The sale of 586,173 units resulted in the issuance of: (1) 4,689,384 shares of common stock; (2) 4,689,384 warrants to purchase a total of 4,689,384 shares of common stock at an exercise price of $1.00 per warrant; (3) 1,172,346 warrants to purchase a total of 1,172,346 shares of common stock at an exercise price of $1.25 per warrant; and (4) 1,172,346 warrants to purchase a total of 1,172,346 shares of common stock at an exercise price of $1.63 per warrant.

Lightspace has entered into a Registration Rights Agreement with the purchasers of the equity units, whereby we have agreed to file a registration statement, within 45 days of the closing, to register for resale the shares of common stock, warrants and shares of common stock issuable upon exercise of the warrants, included in the units issued in the private placement to investors and the financial advisor.

In connection with the sale of the equity units, Lightspace paid Griffin Securities, Inc., the financial advisor for the private placement, a fee in the amount of $187,575 and issued to Griffin Securities a purchase warrant exercisable for 58,617 equity units, in the same form sold in the private placement, at an exercise price of $6.40 per unit.

Lightspace used a portion of the net proceeds from the private placement to fund the acquisition of the emagipix technology by the payment the cash purchase price of $300,000. The balance of the net proceeds will be used for general working capital purposes, including payment of the expenses of registering the private placement units for resale.

(2) Technology Acquisition

On April 30, 2007, LEC completed the acquisition of the emagipix technology. In connection with the acquisition, the developer of the emagipix technology, Mr. Hoch, (a former officer and co-founder of Lightspace Corporation and the principal owner of Illumination Design Works, Inc.), re-commenced employment with Lightspace. Upon employment with Lightspace as Chief Scientist, the Company granted Mr. Hoch options to purchase 250,000 shares of common stock at an exercise price of $0.80 per share.

The $950,000 convertible term secured non-recourse note bears interest a 5% per annum, payable yearly, and is due and payable on April 30, 2011. The note is secured by a pledge of 67% the stock of LEC. The principal of the note is convertible at any time up and until April 30, 2011, at the option of the holder, into the common stock of Lightspace Corporation at a conversion price of $0.80 per share. Upon the occurrence of certain defined events of default by the noteholder, Lightspace has the right to convert the note to common stock at the lower of the conversion price of $0.80 or current market price of the common stock.

We estimate that the cost to complete the development of the emagipix technology will be between $1.5 million and $2.0 million. We further expect that the technology will be commercially available within three years. Lightspace accounted for the acquisition of the emagipix technology as the acquisition of in process research and development and recorded a charge to operations in the June 30, 2007 quarter approximating $1,302,000, which included legal fees incurred in connection with the acquisition.

(3) Pro Forma Statements of Operations

The unaudited pro forma statements of operations for the year ended December 31, 2006 and the quarter ended March 31, 2007 have been adjusted to give effect to the April 30, 2007 acquisition of the emagipix technology and the April 30, 2007 private placement of 586,173 equity units, as if such transactions had occurred as of January 1, 2006.

The unaudited pro forma statement of operations for the year ended December 31, 2006 includes a charge to operations of $1,302,036 related to the acquisition of the emagipix technology, and an increase to research and development operating expenses of $450,000 for the estimated expenses that would have been incurred in the 2006 year related to the development of the emagipix technology, if the acquisition had occurred as of January 1, 2006. The result of these pro forma adjustments was to increase the historical 2006 year net loss from $2,708,420 to a pro forma 2006 year net loss of $4,460,456. Due to the significantly larger number of weighted average common shares outstanding for the pro forma statement of operations for year ended December 31, 2006, 10,022,765, as compared to 5,333,381 for the historical statement of operations for year ended December 31, 2006, pro forma basic and diluted net loss per share for the year ended December 31, 2006 was $0.45 as compared to historical basic and diluted net loss per share of $0.51 for the year ended December 31, 2006.

The unaudited pro forma statement of operations for the quarter ended March 31, 2007 includes an increase to research and development operating expenses of $175,000 for the estimated expenses that would have been incurred in the March 2007 quarter related to the development of the emagipix technology, if the acquisition had occurred as of January 1, 2006. The result of this pro forma adjustment was to increase the historical net loss for the quarter ended March 31, 2007 from $732,490 to a pro forma net loss of $907,490. Due to the significantly larger number of weighted average common shares outstanding for the pro forma statement of operations for quarter ended March 31, 2007, 15,282,495, as compared to 10,593,111 for the historical statement of operations for quarter ended March 31, 2007, pro forma basic and diluted net loss per share for the quarter ended March 31, 2007 was $0.06 as compared to historical basic and diluted net loss per share of $0.07 for the quarter ended March 31, 2007.

MANAGEMENT’S DISCUSSSION AND ANALYSIS OF THE RESULTS

OF OPERATIONS AND FINANCIAL CONDITION

The following discussion of our results of operations and financial condition should be read in conjunction with the selected historical data and the historical financial statements and notes thereto included elsewhere herein. This discussion contains forward-looking statements that relate to future events and our future financial performance. These statements involve known and unknown risks, uncertainties and other factors, including those set forth in the section entitled “Risk Factors” and elsewhere herein. Our actual results and performance may be materially different from any future results or performance implied by these forward-looking statements.

Overview

Lightspace provides interactive lighting entertainment products to family entertainment centers, retail stores, theme parks, fashion shows, nightclubs, special events, stage lighting and sound providers, health clubs and architectural lighting and design. Our current product lines include: (a) Lightspace Play, an interactive 36 tile gaming platform for children and adult recreation; (b) Lightspace Dance, an interactive floor, generally in sizes of 86 tiles and larger, that displays customizable lights and effects; and (c) Lightspace Design, an interactive tile system that displays customizable lights and video effects that can be mounted on any flat surface.

Lightspace received the first significant investor equity funding, $1,386,000, in July and December of 2003 and commenced operations. With this funding, and an additional funding of $600,000 through the issuance of convertible notes in April 2004, we were able to engage contract manufacturers for the initial production run of 100 interactive tiles and subsequent production of interactive tiles, hire sales and marketing staff, introduce the Lightspace products at trade shows, expand the research and development department personnel and budget, and lease facilities for operations. From December 2003 to June 2004, Lightspace increased employment levels from five employees to 27 employees to pursue sales leads, to support the installation and maintenance of our products, and to design improvements to the current product and to develop new product offerings. Lightspace’s initial product offering, Lightspace Dance, was complemented with the introduction of Lightspace Play during this period.

In March of 2004, we began to experience significant manufacturing problems at the contract manufacturer. The manufacturing problems encompassed design errors, faulty parts and improper assembly. These problems increased the production cost and significantly reduced the yield of finished interactive tiles. The reduction in available finished product restricted us from selling products to customers and pursuing sales leads. These manufacturing problems continued until product design changes and quality control procedures were fully implemented in early 2005. The effect of the manufacturing problems and consequent lost sales resulted in Lightspace using more cash resources than planned for a longer period of time to fund operations and product improvements. Our cash situation had become critical, and by September of 2005, employment levels had decreased to 11 employees. More significantly, without the required funding, we were unable from March 2005 to September 2005 to engage a contract manufacturer for the production of interactive tiles.

With the proceeds of private financings from September 2005 to March 2006, Lightspace obtained sufficient capital to restart the production of interactive tiles. In the 2006 year we manufactured 1,350 interactive tiles.

During the year ended December 31, 2006, as more fully described in the section, Liquidity, Capital Resources and Cash Flow, we completed a restructuring of our debt and preferred stock and two equity financings, the second financing being our initial public offering.

During the first quarter of 2007, we completed and introduced a new generation of our interactive tile with added software enhancements. The new interactive tile and enhanced software, in addition to increased product reliability and reduced manufacturing cost, is significantly more illuminative and is now available in clear plastic in addition to the traditional off white.

On April 11, 2007, we commenced the private placement of up to 600,000 equity units at an offering price of $6.40 per unit. Each equity unit consists of: (1) eight shares of common stock; (2) eight unit warrants to purchase a total of eight shares of common stock at an exercise price of $1.00 per warrant; (3) two unit warrants to purchase a total of two shares of common stock at an exercise price of $1.25 per warrant; and (4) two unit warrants to purchase a total of two shares of common stock at an exercise price of $1.63 per warrant. On April 30, 2007 we closed the offering period for our equity units. We sold 586,173 units at the offering price of $6.40 per unit, resulting in aggregate proceeds of $3,751,507. After estimated expenses of the offering of $311,507, the net proceeds to Lightspace were approximately $3,440,000.

On April 30, 2007, we completed the acquisition of the in process development emagipix technology from Illumination Design Works, Inc. Emagipix technology is an interactive lighting technology that utilizes electroluminescent sheets. The purchase price for the emagipix technology consisted of a cash payment of $300,000 and the issuance of a $950,000 convertible term secured non-recourse note. In connection with the acquisition, the developer of the emagipix technology (a former officer and co-founder of Lightspace Corporation and the principal owner of Illumination Design Works, Inc.), re-commenced employment with Lightspace. We accounted for the acquisition of the emagipix technology as the acquisition of in process research and development and recorded a charge to operations in the June 30, 2007 quarter of $1,302,000, which included legal fees incurred in connection with the acquisition.

Lightspace has incurred net operating losses and negative operating cash flows since inception. At December 31, 2006 and March 31, 2007, we had an accumulated retained deficit of $10,311,635 and $11,044,125. At March 31, 2007 we had a stockholders’ deficit of $395,235 and a negative current working capital position of $665,290. We expect to incur additional losses and negative operating cash flows through at least the September quarter of 2007. We will continue thereafter to incur losses and negative operating cash flows until our revenue growth reaches that level that is able to support our operating expenses.

Our long-term success is dependent on obtaining sufficient capital to fund operations and development of new products, bringing such products to the worldwide market, and obtaining sufficient sales volume to be profitable. To achieve these objectives, we may be required to raise additional capital through public or private financings or other arrangements. There can be no assurance that such financings will be available on terms attractive to Lightspace, if at all. Such financings may be dilutive to stockholders and may contain restrictive covenants.

Results of operations for the years ended December 31, 2006 and 2005

Revenue and Operating Results

For the year ended December 31, 2006, revenue was $848,201, a decrease of $177,405, or 17%, from revenue of $1,025,606 recorded in the year ended December 31, 2005. The net loss for the year ended December 31, 2006 was $2,708,420 as compared to the net loss for the year ended December 31, 2005 of $2,914,507. The net loss for the year ended December 31, 2006 has been reduced by a one-time gain of $402,298 related to the stockholders’ debt and equity conversion on April 27, 2006, as discussed under the section Liquidity, Capital Resources and Cash Flow.

Due to the significantly larger number of weighted average common shares outstanding in the year ended December 31, 2006, 5,333,381, as compared to 971,182 in the year ended December 31, 2005, basic and diluted net loss per share for the year ended December 31, 2006 was $0.51 as compared to basic and diluted net loss per share of $3.00 for the year ended December 31, 2005.

The revenue for the year ended December 31, 2006 was comprised of sales of products, $780,843, and other revenue of $67,358, as represented by deferred maintenance revenue, sales of miscellaneous parts and other services. In the year ended December 31, 2006, there were 16 new product installation sites, representing 1,068 interactive tiles, comprised of eight Lightspace Play installations, five Lightspace Design installations, and three Lightspace Dance installations. The revenue for the year ended December 31, 2005 was comprised of the sales of products, $989,396, and other revenue of $36,210, as represented by deferred maintenance revenue and other services. In the year ended December 31, 2005, there were 14 new product installation sites, representing 1,370 interactive tiles, comprised of nine Lightspace Play installations five Lightspace Dance installations.

The decline in revenues for the year ended December 31, 2006, $848,201, as compared to the year ended December 31, 2005, $1,025,606, is due principally to the following: (1) the lack of interactive tiles available for sale (By the end of October of 2005 we had sold all available inventory of interactive tiles and did not receive the first production run of five hundred interactive tiles from our contract manufacturer until the first quarter of 2006.); and (2) the inability to pursue the normal sales process wherein leads are pursued, demonstrations made, and terms and dates of installation are agreed upon, due to the lack of available inventory. During the first six months of 2006, we added three sales personnel to our staff and recommenced marketing and advertising of our products.

Our product backlog as of December 31, 2006 was $208,134, representing three hundred forty three (343) interactive tiles. Product backlog as of December 31, 2005 was $26,400, representing thirty six (36) interactive tiles. Cancellation of a signed contract or order included in product backlog requires the consent of Lightspace.

For the year ended December 31, 2006, sales of our products and recognition of other revenue were made to customers in the United States, in the amount of $567,827, to customers in Asia, in the amount of $141,851, and to customers in other international countries, $138,523. For the year ended December 31, 2005, sales of our products and recognition of other revenue were made to customers in the United States, in the amount of $748,800, to customers in Asia, in the amount of $114,675, to a Canadian customer, in the amount of $121,750, and to customers in other international countries, in the amount of $40,381.

Lightspace had ten different customers that each comprised more than 10% of product sales through the three years ended December 31, 2006. In year ended December 31, 2006, two customers accounted for $367,851, or approximately 47% of total product sales. In each of the years ended December 31, 2005 and 2004, four different customers accounted for $668,782, or approximately 68%, and $346,318, or approximately 91%, respectively of total product sales. We believe that the high percentage of product sales in each of the aforementioned periods to a small number of customers is the result of the low number of sales and the large dollar values of certain sales and is expected at this point of the Company’s operating history.

Product Cost and Gross Margin

For the years ended December 31, 2006 and 2005, Lightspace recorded negative gross margins of $21,881, or 3%, and positive gross margins of $200,798, or 21%, respectively. The year ended December 31, 2006 includes a provision of $196,371 for obsolete inventory component parts and interactive tiles resulting from engineering design changes to be incorporated into the production of interactive tiles in the first quarter of 2007. In addition to the 2006 provision for obsolescence, another factor affecting the significant decline in the 2006 gross margin is that the fixed cost of our manufacturing and customer service organizations, as discussed hereafter, was spread over a lower number of sales of interactive tiles, 1,068 tiles in the year ended December 31, 2006 versus 1,370 tiles in the year ended December 31, 2005. Due to the low dollar volume of sales in each year, these margin rates are not representative of margin rates that may be achieved if we achieve higher volume levels.

Product cost includes the direct cost of materials, associated freight charges, and the allocated per unit cost of the contractor’s manufacturing labor, overhead and profit associated with products sold. For the most part, these costs are variable and increase or decrease with volume. Product cost also includes Lightspace’s personnel and related expenses assigned to manufacturing and customer service. These latter costs tend to be a fixed cost that decreases on a per unit basis as volume increases.

While not apparent due to the low dollar volume of sales in the year ended December 31, 2006, we were able to achieve a 17% reduction in the cost of an interactive tile by changing certain component part suppliers, eliminating several component parts, and negotiating a supply contract with a new contract manufacturer. We expect that with volume increases, we may be able to achieve further reductions in both the cost of the interactive tiles and other system components that will offset the increased cost of plastic used in our products due to higher oil prices.

Operating Expenses

Research and development spending was $1,001,539 for the year ended December 31, 2006 as compared to $895,942 for the year ended December 31, 2005, an increase of $105,597, or 12%. As we previously mentioned, to conserve cash subsequent to March 2005, we significantly reduced all department spending. 2005 quarterly spending for research and development decreased from a high of $268,795 in the quarter ended March 2005 to approximately $185,000 for each of the quarters ended September and December 2005. For the most recent quarter ended December 31, 2006, research and development spending had increased to $274,830. The increased 2006 research and development spending is related to the two engineers hired in 2006 and spending for new product development. We intend to hire two additional engineers in 2007 to assist in new product development. Additionally, we have budgeted approximately $286,000 in 2007 research and development spending, exclusive of staff salaries, for the design, development and testing of a new generation of Lightspace products.

Selling and marketing expenditures were $1,033,715 for the year ended December 31, 2006 as compared to $648,315 for the year ended December 31, 2005, an increase of $385,400, or 59%. Selling and marketing expenditures were significantly reduced after the quarter ended March 2005 to conserve cash. The increase in sales and marketing spending in the year ended December 31, 2006 is related to the 2006 hiring of three sales/customer service employees, and increased spending for trade shows, advertising, demonstration interactive tile floors and employee travel expenses.

Administrative expenditures were $772,134 for the year ended December 31, 2006 as compared to $1,019,189 for the year ended December 31, 2005, a decrease of $247,055, or 24%. In the year ended December 31, 2005, administrative expenses were impacted by approximately $292,000 of legal and other consulting fees incurred in connection with our short-term note financings and a contemplated, but subsequently aborted, merger with a public company. Administrative expenses were further impacted in September of 2005 by: (1) the restoration of our former CEO’s salary to $250,000 per year from prior nominal amounts; and (2) the fair value of common stock warrants, $54,849, issued in connection with the extension of payment terms of a demand note and personal guarantees of Lightspace debt obligations. In the year ended December 31, 2006 partially offsetting the savings from the non-reoccurrence of the 2005 legal, consulting and warrant expenses discussed above, was the addition of permanent accounting and finance personnel.

On April 21, 2006, we entered into a severance agreement with our former Chief Executive Officer, pursuant to which he resigned as an officer, director and employee of Lightspace effective March 31, 2006. Under the agreement, we paid him his accrued wages and vacation pay, reimbursed him for recorded expenses incurred on behalf of Lightspace aggregating $47,636, paid him $10,000 as severance, and paid him $20,000 as a non-refundable advance payment for one-hundred (100) hours of consulting work. We also paid $20,000 against an existing accounts payable balance due to his affiliate, Immersive Productions.

Interest Expense

Net interest expense for the year ended December 31, 2006 was $281,449 as compared to $551,859 for the year ended December 31, 2005, a decrease of $270,410, or 49%. The decrease in interest expense for the year ended December 31, 2006 is due to the conversion to common stock and common stock warrants on April 27, 2006 of $2,701,853 in principal amount of convertible and demand notes, and the conversion to common stock and common stock warrants on May 3, 2006 of $2,400,000 in principal amount of senior secured notes, all as discussed in Liquidity, Capital Resources and Cash Flow below.

Results of operations for the years ended December 31, 2005 and 2004

Revenue and Operating Results

For the year ended December 31, 2005 product sales aggregated $989,396, an increase of 198% over 2004 product sales of $332,117, and other 2005 revenue, principally deferred maintenance revenue, aggregated $36,210, a decrease of 25% over 2004 other revenue of $48,404. These results reflect the small number of our sales to date and the brief period in which we have been operating. There were 14 new product installation sites in 2005, representing 1,370 interactive tiles, comprised of five Lightspace Dance installations and nine Lightspace Play installations.

The net loss for the year ended December 31, 2005 was $2,914,507 as compared to the net loss for the year ended December 31, 2004 of $4,104,377. The basic and diluted net loss per share for the year ended December 31, 2005 was $3.00 as compared to $4.25 for the year ended December 31, 2004.

Quarterly 2005 revenues decreased significantly from a high of $632,402 for the March quarter to $150,963, $183,070 and $59,171 for the June, September and December 2005 quarters, respectively. The decline in quarterly revenues was due to the inability of Lightspace to secure additional adequate financing during this period. To conserve cash, we were required to terminate sales and marketing personnel, significantly restrict marketing expenditures, and in March 2005 stop the production of interactive tiles. Fourth quarter sales of $59,171 used all available inventory of interactive tiles. With the new funding round that commenced in September 2005, we engaged a contract manufacturer to produce 500 interactive tiles. These interactive tiles were delivered in the first quarter of 2006.

Lightspace commenced operations in the latter half of 2003 and recorded its first sale in January of 2004. Initially, our sole product offering was Lightspace Dance. During the first quarter of 2004, Lightspace introduced the Lightspace Play product. Revenue from the sale of products in 2004 was $332,117. There were five product installation sites, representing 466 interactive tiles, comprised of three Lightspace Dance installations and two Lightspace Play installations. Other 2004 revenue in the amount of $48,404 represents income associated with short-term rentals of Lightspace products and the recognition of deferred maintenance revenue on a straight-line basis over the term of the contract.

All 2004 product sales were made to customers in the United States. Sales of products and recognition of deferred maintenance revenue for the year ended December 31, 2005 were made to customers in the United States, $748,800, and to international customers, $276,806, including a $121,750 sale to a customer located in Canada. In each year, due to the large dollar value of certain sales and the level of sales volume, four different customers each comprised more than 10% of revenues or accounts receivable. For the years ended December 31, 2005 and 2004, sales to individual customers that comprised more than 10% of revenues aggregated $668,782 and $346,318, respectively.

Product Cost and Gross Margin

For the years ended December 31, 2005 and 2004, Lightspace recorded gross margins of $200,798, or 20%, and a negative $282,920, or negative 74%, respectively. Due to the low dollar volume of sales, these margin rates are not representative of margin rates that may be achieved if we achieve higher volume levels.

Product cost includes the direct cost of materials, associated freight charges, and the allocated per unit cost of the contractor’s manufacturing labor, overhead and profit associated with products sold. For the most part, these costs are variable and increase or decrease with volume. Product cost also includes Lightspace’s personnel and related expenses assigned to manufacturing and customer service. These latter costs tend to be fixed costs that decrease on a per unit basis and as a percentage of revenue as volume increases.

Operating Expenses

Research and development, selling and marketing and administrative expenses in 2004 increased significantly to $3,592,871 from the 2003 level of $474,713. The principal components of this increased spending were the addition of 22 employees to these departments from December 2003 to June 2004, rental of office space in March 2004 at approximately $26,000 per month, increased marketing trade show expenditures, and the expansion of the research and development project budget for product design improvements and development of new products.

In March 2004, as previously mentioned, we began to experience production problems in the manufacturing of the interactive tiles. The consequences of the manufacturing problems, the lack of saleable inventory and higher production costs, coupled with our inability at that time to secure adequate financing, required us to significantly reduce spending in all departments to conserve cash. Company wide employment levels were reduced from a high of 27 employees at June 30, 2004 to 11 employees at September 30, 2005. In addition to the reduction of employees, we were required to significantly reduce all other departments’ spending. As a result, research and development expenditures decreased to $895,942 in 2005 from $1,543,653 in 2004, a 42% reduction, and selling and marketing expenditures decreased to $648,315 in 2005 from $1,005,569 in 2004, a 36% reduction. Administrative expenses, while experiencing the same internal spending reductions as the other departments, were $1,019,189 in 2005, slightly less than the $1,043,649 recorded in 2004. In the year ended December 31, 2005, administrative expenses were impacted by approximately $292,000 of legal and other consulting fees incurred in connection with our short-term note financings and a contemplated, but subsequently aborted, merger with a public company. Administrative expenses were further impacted in September of 2005 by: (1) the restoration of our former CEO’s salary to $250,000 per year from prior nominal amounts; and (2) the fair value of common stock warrants, $54,849, issued in connection with the extension of payment terms of a demand note and personal guarantees of Lightspace debt obligations.

The resulting effect of these cash conservation measures was that overall departmental expenditures for the year ended December 31, 2005 were $2,563,446, approximately $1,029,000, or 29%, less than such expenditures, $3,592,871, in 2004.

Interest Expense

Net interest expense has increased on a yearly basis from $5,350 in 2003 to $228,586 in 2004 to $551,859 in 2005. The progressive increase in interest expense is directly related to our increased short-term borrowings to fund operating expenses and the production of inventory. At December 31, 2003 total borrowings were $237,000 increasing to $2,364,247 at December 31, 2004 and to $4,639,234 at December 31, 2005. In addition to the stipulated interest rates associated with the increase in total borrowings, interest expense in the years 2004 and 2005 was further impacted by charges of $71,657 and $88,200, respectively, related to the fair value of preferred and common stock warrants issued in connection with the placement of convertible debt.

Results of Operations for the Quarters Ended March 31, 2007 and 2006

Revenue and Operating Results

For the quarter ended March 31, 2007, revenue was $333,959, an increase of $298,395 from revenue of $35,564 recorded in the quarter ended March 31, 2006. The net loss for the quarter ended March 31, 2007 was $732,490, as compared to a net loss for the quarter ended March 31, 2006 of $913,792. Due to the significantly larger number of weighted average common shares outstanding in the quarter ended March 31, 2007, 10,593,111, as compared to 977,182 in the quarter ended March 31, 2006, basic and diluted net loss per share for the quarter ended March 31, 2007 was $0.07 as compared to basic and diluted net loss per share of $0.94 for the quarter ended March 31, 2006.

The revenue for the quarter ended March 31, 2007 was comprised of revenue from the sale of products, $316,534, and other revenue of $17,425, as represented by deferred maintenance revenue, sales of miscellaneous parts and other services. In the quarter ended March 31, 2007, there were 12 Lightspace Play or Lightspace Design new installation sites and one Lightspace Dance new installation site, representing 509 interactive tiles. The revenue for the quarter ended March 31, 2006 was comprised of revenue from the sale of products, $24,905, and other revenue of $10,659, as represented by deferred maintenance revenue, sales of miscellaneous parts and other services. In the quarter ended March 31, 2006, there was one Lightspace Play new installation site, representing 36 interactive tiles. The quarter ended March 31, 2006 was impacted by: (1) the lack of interactive tiles available for sale (By the end of October of 2005 we had sold all available inventory of interactive tiles and did not receive the first production run of 500 interactive tiles from our contract manufacturer until the first quarter of 2006.); and (2) the normal sales process wherein leads are pursued, demonstrations made, and terms and dates of installation are agreed upon (The sales staff at Lightspace had been reduced to two employees during 2005 due to the critical cash situation. It was until late in the March quarter of 2006 and in the second quarter that three additional sales staff were hired.).

Our product backlog at March 31, 2007 was $163,200, representing 261 interactive tiles. We expect that this backlog will be shipped and installed prior to June 30, 2007. Product backlog at December 31, 2006 was $208,134, representing 343 interactive tiles. Cancellation of a signed contract or order included in product backlog requires the consent of Lightspace.

For the quarter ended March 31, 2007, sales of Lightspace products were made to customers in the United States - $220,959; South America - $42,000; Europe - $26,000; Asia - $24,500; and Canada - $20,500. During this period, three Lightspace customers each comprised more than 10% of revenues. Sales to these customers aggregated $126,334 in the 2007 three-month period. For the quarter ended March 31, 2006, a single product sale was made to a customer in the United States.

Product Cost and Gross Margin

For the quarters ended March 31, 2007 and 2006, Lightspace recorded gross margins of $62,694, or 19%, and a negative $51,657, or 145%, respectively. Due to the low dollar volume of sales in each quarter, particularly the quarter ended March 2006, these margin rates are not representative of margin rates that may be achieved if we achieve higher volume levels.

Product cost includes the direct cost of materials, associated freight charges, and the allocated per unit cost of the contractor’s manufacturing labor, overhead and profit associated with products sold. For the most part, these costs are variable and increase or decrease with volume. Product cost also includes our personnel and related expenses assigned to manufacturing and customer service. These latter costs tend to be a fixed cost that decreases on a per unit basis as volume increases.

Operating Expenses

Research and development spending was $250,048 for the quarter ended March 31, 2007 as compared to $226,340 for the quarter ended March 31, 2006. The increased research and development spending when comparing the quarter ended March 31, 2007 to the quarter ended March 31, 2006 of approximately $24,000, or 11%, is principally related to expenditures for final prototypes and external certifications related to the March 2007 product launch of a new generation of our interactive tile with software enhancements. Research and development spending for the 2007 year is forecasted to exceed the amount spent for our 2006 research and development efforts.

Selling and marketing expenditures were $300,943 for the quarter ended March 31, 2007 as compared to $212,633 for the quarter ended March 31, 2006, an increase of $88,310, or 42%. During the 2005 year selling and marketing expenditures were significantly reduced to conserve cash. It was not until the first and second quarters of 2006 that sufficient cash was available to allocate more resources to our selling and marketing efforts. During the six months ended June 30, 2006, we added three sales/customer service employees and increased spending for trade shows, advertising, print publications, and employee travel expenses. We anticipate that additional sales staff will be added in 2007.

Administrative expenses were $232,343 for the quarter ended March 31, 2007 as compared to $272,193 for the quarter ended March 31, 2006, a decrease of $39,850, or 15%. The quarter ended March 31, 2006 include a $30,000 payment under a severance agreement to our former Chief Executive Officer and additional internal financial and accounting expenses incurred in connection with our private and public sales of equity securities in 2006. No such similar expenses were incurred in the March 2007 quarter; however, partially offsetting the lack of such expenses in 2007 is a charge of to administration of approximately $17,500 for stock option compensation.

Interest Expense

Interest expense was $11,850 for the quarter ended March 31, 2007 as compared to $150,969 for the quarter ended March 31, 2006, a decrease of $139,119, or 92%. The decrease in the quarter ended March 31, 2007 interest expense is due to the conversion to common stock on April 27, 2006 of $2,701,853 in principal amount of convertible and demand notes, and the conversion to common stock on May 3, 2006 of $2,488,471 in principal amount and accrued interest of bridge notes, as more fully described in the section, Liquidity, Capital Resources and Cash Flow.

Net Loss

The net loss for the quarter ended March 31, 2007 was $732,490 as compared to a net loss of $913,792 in the quarter ended March 31, 2006. Impacting the quarter ended March 31, 2007, in addition to the preceding discussion, was a charge in the amount of 40,246 related to stock option based compensation. The provisions of Statement of Financial Accounting Standards No. 123(R), Share-Based Payment, were first effective for us in the September 2006 quarter, and accordingly no prior financials periods were affected by this pronouncement. At March 31, 2007, total unrecognized stock based compensation expense related to unvested common stock option grants expected to be charged to operations over the next two and one-quarter years is estimated to be approximately $350,000.

Liquidity, Capital Resources and Cash Flow

Lightspace has incurred net operating losses and negative operating cash flows since inception. At December 31, 2006 and March 31, 2007, we had an accumulated retained deficit of $10,311,635 and $11,044,125, respectively. At March 31, 2007 we had a stockholders’ deficit of $395,235 and a negative current working capital position of $665,290. As discussed hereafter, on April 30, 2007 we completed the private placement of equity units, resulting in net proceeds to Lightspace, after expenses of the offering, of approximately $3,440,000. We expect to incur additional losses and negative operating cash flows through at least the September quarter of 2007. We will continue thereafter to incur losses and negative operating cash flows until our revenue growth reaches that level that is able to support our operating expenses.

Lightspace’s long-term success is dependent on obtaining sufficient capital to fund its operations and development of its products, bringing such products to the worldwide market, and obtaining sufficient sales volume to be profitable. To achieve these objectives, we may be required to raise additional capital through public or private financings or other arrangements. There can be no assurance that such financings will be available on terms attractive to Lightspace, if at all. Such financings may be dilutive to stockholders and may contain restrictive covenants.

Lightspace has funded its operations through March 31, 2007 through the private and public issuances of common stock and warrants, Series A Preferred Stock, borrowings from stockholders and others pursuant to convertible and demand notes, bridge notes and senior notes, and sales of Lightspace products.

On February 9, 2006, we entered into the Securityholder Debt and Equity Conversion and Exchange Agreement (the “Exchange Agreement”) with (1) holders of $1,401,000 in principal amount of convertible notes and $1,538,234 in principal amount of demand notes, (2) holders of 133,732 shares of Series A convertible preferred stock and (3) existing warrantholders to provide for the terms of the debt conversion, preferred conversion and warrant exchange. On April 27, 2006, the conditions for the closing of the Agreement having been met, Lightspace effected the conversion and exchange. Under the terms of the Agreement, (1) the holders of convertible and demand notes received 1,544,865 shares of common stock and exchange warrants to purchase 1,480,849 shares of common stock at exercise prices ranging from $0.80 to $7.50 per share upon conversion of their existing notes and any warrants issued in conjunction therewith, and our former CEO received a contingent promissory note in the principal amount of $237,381; (2) the holders of Series A convertible preferred stock received 160,479 shares of common stock upon conversion of their Series A convertible preferred stock; and (3) the holders of other existing warrants received exchange warrants to purchase 41,063 shares of common stock at an exercise price of $7.50 per share. As a result of the closing of the Agreement, we recorded a one-time non cash net gain of $402,298.

On April 27, 2006, Lightspace and the holders of the senior secured bridge notes agreed to convert the outstanding principal and accrued interest thereon, $2,488,471, into equity units at a conversion price of $6.40 per unit. On May 3, 2006, we issued 388,821 equity units, and a small number of shares of common stock and unit warrants representing fractional units, in exchange for the surrender of all of the bridge notes. Each equity unit consists of: (1) eight shares of common stock; (2) eight unit warrants to purchase a total of eight shares of common stock at an exercise price of $1.00 per warrant; (3) two unit warrants to purchase a total of two shares of common stock at an exercise price of $1.25 per warrant; and (4) two unit warrants to purchase a total of two shares of common stock at an exercise price of $1.63 per warrant. In aggregate we issued to the bridge noteholders in this transaction: (1) 3,110,585 shares of common stock; (2) 3,110,585 unit warrants to purchase a total of 3,110,585 shares of common stock at an exercise price of $1.00 per warrant; (3) 777,646 unit warrants to purchase a total of 777,646 shares of common stock at an exercise price of $1.25 per warrant; and (4) 777,646 unit warrants to purchase a total of 777,646 shares of common stock at an exercise price of $1.63 per warrant. The warrants are exercisable at the option of the holder at any time up until April 30, 2011, at which date the warrants expire.

In connection with the conversion of the senior secured bridge notes, the Lightspace incurred a $312,000 fee due to Griffin Securities, Inc., the placement agent for this transaction. Griffin Securities also acted as the underwriter for our public sale of equity securities, discussed below, and as the financial advisor for our private sale of equity securities on April 30, 2007.

In 2006, we filed a Registration Statement on Form S-1, and amendments thereto, with the Securities and Exchange Commission to register for sale a minimum of 450,000 units (as described above), on a best efforts all or none basis, and an additional 150,000 units on a best efforts basis, for a maximum of 600,000 units at a price per unit of $6.40. The Registration Statement was declared effective by the Securities and Exchange Commission on October 4, 2006 (Securities and Exchange File No. 333-131857). On November 2, 2006 we closed the public offering period for the sale of our equity units. We sold 600,000 units at an offering price of $6.40 per unit, resulting in aggregate proceeds to Lightspace of $3,840,000. After repayment of principal and interest due on senior notes in the aggregate amount of $1,409,000 and expenses of the offering of $468,000, the net proceeds to Lightspace were approximately $1,963,000. Each equity unit consists of: (1) eight shares of common stock; (2) eight unit warrants to purchase a total of eight shares of common stock at an exercise price of $1.00 per warrant; (3) two unit warrants to purchase a total of two shares of common stock at an exercise price of $1.25 per warrant; and (4) two unit warrants to purchase a total of two shares of common stock at an exercise price of $1.63 per warrant. The sale of 600,000 units sold include an aggregate of: (1) 4,800,000 shares of common stock; (2) 4,800,000 unit warrants to purchase a total of 4,800,000 shares of common stock at an exercise price of $1.00 per warrant; (3) 1,200,000 unit warrants to purchase a total of 1,200,000 shares of common stock at an exercise price of $1.25 per warrant; and (4) 1,200,000 unit warrants to purchase a total of 1,200,000 shares of common stock at an exercise price of $1.63 per warrant. The warrants are exercisable at the option of the holder at any time up until April 30, 2011, at which date the warrants expire.

In connection with the sale of the public equity units, we issued to Griffin Securities, Inc., the underwriter, a unit purchase warrant exercisable for 102,000 units at an exercise price of $7.68 per unit. Each underwriter unit consists of: (1) eight shares of common stock; (2) eight unit warrants to purchase a total of eight shares of common stock at an exercise price of $1.00 per warrant; (3) two unit warrants to purchase a total of two shares of common stock at an exercise price of $1.25 per warrant; and (4) two unit warrants to purchase a total of two shares of common stock at an exercise price of $1.63 per warrant. The units to be issued to Griffin Securities upon exercise of the unit purchase warrant are the same in all respects as the units sold in the public placement.

On April 30, 2007 we sold in a private placement 586,173 equity units, in the same form sold in our public offering, at the offering price of $6.40 per unit, resulting in aggregate proceeds to Lightspace of $3,751,507. After estimated expenses of the offering of $311,507, the net proceeds to Lightspace were approximately $3,440,000. The sale of 586,173 units resulted in the issuance of: (1) 4,689,384 shares of common stock; (2) 4,689,384 warrants to purchase a total of 4,689,384 shares of common stock at an exercise price of $1.00 per warrant; (3) 1,172,346 warrants to purchase a total of 1,172,346 shares of common stock at an exercise price of $1.25 per warrant; and (4) 1,172,346 warrants to purchase a total of 1,172,346 shares of common stock at an exercise price of $1.63 per warrant. The warrants are exercisable at the option of the holder at any time up until April 30, 2012, at which date the warrants expire. In the event of a division of our common stock, the warrants will be adjusted proportionately. The warrants have been classified permanently within stockholders’ equity, as upon exercise, the warrant holder can only receive the specified number of common shares. We entered into a Registration Rights Agreement with the purchasers of the equity units, whereby we have agreed to file a registration statement, within 45 days of the closing, to register for resale the shares of common stock, warrants and shares of common stock issuable upon exercise of the warrants, included in the equity units issued in the private placement to investors and the financial advisor.

In connection with the sale of the equity units, Lightspace paid Griffin Securities, Inc., the financial advisor for the private placement, a fee in the amount of $187,575 and issued to Griffin Securities a purchase warrant exercisable for 58,617 units, in the same form sold in the private placement, at an exercise price of $6.40 per unit.

We used a portion of the net proceeds from the private placement to complete the acquisition of the emagipix technology by the payment of the cash purchase price of $300,000. The balance of the net proceeds will be used for general working capital purposes, including payment of the expenses of registering the private placement units for resale.

We believe that the proceeds from the April 30, 2007 private placement, together with anticipated revenues from sales of our products, will be sufficient to meet our liquidity requirements for the next 12 months.

As a result of the private placement, issued and outstanding shares of Lightspace’s common stock at April 30, 2007 increased to 15,282,495 from 10,593,111 issued and outstanding shares at December 31, 2006 and March 31, 2007. Additionally, issued and outstanding common stock warrants at April 30, 2007 were 23,634,205, exercisable at prices that range from $0.80 to $7.50. At December 31, 2006 and March 31, 2007, we had issued and outstanding common stock warrants in the aggregate amount of 15,427,789, exercisable at prices that range from $0.80 to $7.50.

Technology Acquisition

Income Taxes

At December 31, 2005 and 2006 and March 31, 2007, Lightspace had operating loss carryforwards of approximately $6,684,000, $3,384,000 and $4,100,000, respectively, available to offset future taxable income for United States federal and state income tax purposes. At December 31, 2006 and March 31, 2007, approximately $1,846,000 of the operating loss carryforwards were restricted as to yearly usage, as discussed hereafter. The United States federal tax operating loss carryforwards expire commencing in 2021 through 2027. The state tax operating loss carryforwards expire commencing in 2007 through 2011. Additionally, at December 31, 2006 and March 31, 2007, the Company had research and development credit carryforwards of approximately $69,000 and $74,000, respectively, available to be used as a reduction of federal income taxes.

The deferred tax asset related to the operating loss carryforwards, tax credits and other items deductible against future taxable income was $3,068,415, $1,611,591 and $1,904,666 at December 31, 2005 and 2006 and March 31, 2007, respectively. We have provided a valuation allowance at those dates equal to the full amount of the deferred tax asset, and will continue to fully reserve the deferred tax asset until it can be ascertained that all or a portion of the asset will be realized.

Our ability to use the operating loss carryforwards and tax credit carryforwards to offset future taxable income is subject to restrictions enacted in the United States Internal Revenue Code of 1986. These restrictions severely limit the future use of the loss carryforwards if certain ownership changes described in the code occur. The common stock ownership changes occurring as a result of the securityholder debt and equity conversion on April 27, 2006 and the conversion of senior secured notes on May 3, 2006 have caused defined ownership changes that have resulted in reductions and in limitations in the use of the operating loss and tax credit carryforwards. The value of the operating loss carryforwards at the date of the ownership change, $6,313,000, was reduced to approximately $1,846,000. Additionally, in future years, such reduced operating loss carryforwards of $1,846,000 can be used only to offset approximately $90,000 of taxable income per year, if any. The tax credit carryforwards at the date of the ownership change were similarly reduced and restricted. Our unrestricted operating loss carryforwards at March 31, 2007 were approximately $2,254,000. The common stock ownership changes occurring as a result of our initial public offering on November 2, 2006 and the private placement of equity units on April 30, 2007 have caused restrictions and limitations in the use of the unrestricted operating loss carryforwards at March 31, 2007. Therefore, in future years, Lightspace may be required to pay income taxes even though significant operating loss and tax credit carryforwards exist.

Manufacturing Operations

We currently contract for the production and assembly of interactive tiles from an independent manufacturing company and have had discussions with other contract manufacturers as secondary sources for the production and assembly of our interactive tiles. The current contract manufacturer is ISO certified and, to date, we have not experienced either quality or production difficulties. The production run is scheduled for a minimum of 200 interactive tiles per week, with the ability to increase the weekly production to 400 to 500 interactive tiles, if required.

Deferred Revenue and Backlog

Deferred revenue is represented by: (1) advance deposits received from customers for the future purchase and installation of a Lightspace system; and (2) the balance of deferred maintenance revenue to be recognized as income over the remaining term of the maintenance contract. Customer deposits are the segment of backlog that, in addition to being supported by a signed contract, is also supported by a customer advance payment. Our product backlog at March 31, 2007 and December 31, 2006 was $163,200 (261 interactive tiles) and $208,134 (343 interactive tiles), respectively, and was comprised substantially of customer advance payments.

Off-Balance Sheet Arrangements

Lightspace has no off-balance sheet arrangements other than normal lease arrangements.

At December 31, 2006, we leased our office and manufacturing space and certain office equipment. Total rent expense for each of the years ended December 31, 2004, 2005 and 2006 and the quarters ended March 31, 2006 and 2007 was $276,468, $329,754, $364,875, $95,122 and $81,946, respectively.

Effective May 1, 2006, the Lightspace entered into a five-year lease for approximately 16,000 square feet to be used for office and manufacturing operations. The terms of this new lease provide for average annual base rental payments of approximately $293,500 per year, plus an allocated percentage of the increase in the building operating costs over defined base year operating costs.

The table below sets forth our known contractual obligations as of December 31, 2006.

Contractual Obligation	Payments Due by Period
	Total		1 Year		2-3 Years		4-5 Years		Thereafter

Recent Accounting Pronouncements

In December 2004, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123(R), Share-Based Payment. This statement addresses accounting for stock-based compensation arrangements, including shares issued to employees and directors under various stock-based compensation arrangements. This statement will require us to use the fair value method, rather than the intrinsic-value method, to determine compensation expense for all stock-based arrangements. Additionally, Lightspace will no longer be permitted to calculate stock-based compensation utilizing the minimum value method. This statement was effective for Lightspace in 2006 for all prospective grants of stock-based compensation awards and modification of prior stock awards. Adoption of this statement will increase compensation costs recognized in our statement of operations from historical levels for all prospective awards granted and modification of prior stock awards.

Critical Accounting Policies and Estimates

The financial statements of Lightspace are prepared in conformity with accounting principles generally accepted in the United States of America. These accounting principles require us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements. Lightspace is also required to make certain judgments that affect the reported amounts of revenues and expenses during the reporting period. On an on-going basis, we evaluate our estimates and the process under which those estimates are formulated. Lightspace develops its estimates based upon historical experience as well as assumptions that are considered to be reasonable under the circumstances. Actual results may differ from these estimates.

We believe that the following critical accounting policies impact the more significant judgments and estimates used in the preparation of the financial statements:

Revenue Recognition. Lightspace recognizes revenue from the sale of its entertainment systems when all of the following conditions have been met: (1) evidence exists of an arrangement with the customer, typically consisting of a purchase order or contract; (2) our products have been delivered and risk of loss has passed to the customer; (3) we have completed all of the necessary terms of the contract including but not limited to, installation of the product and training; (4) the amount of revenue to which we are entitled is fixed or determinable; and (5) we believe it is probable that it will be able to collect the amount due from the customer. To the extent that one or more of these conditions has not been satisfied, Lightspace defers recognition of revenue. Revenue from maintenance contracts is recorded on a straight-line basis over the term of the contract. An allowance for uncollectible receivables is established by a charge to operations, when in our opinion it is probable that the amount due to Lightspace will not be collected.

Inventory Reserve - A reserve for obsolete and slow moving inventory is established by a charge to product cost when, in the opinion of the Company, engineering design changes, the introduction of new products or forecasted selling prices have reduced the net realizable value of such inventory below cost.

Warranty Reserve. Our products are warranted against defects for twelve months following the sale. Reserves for potential warranty claims are provided at the time of revenue recognition and are based on several factors including historical claims experience, current sales levels and Lightspace’s estimate of repair costs.

Stock-Based Compensation. Effective January 1, 2006, we adopted the provisions of Financial Accounting Standards No. 123(R), Share-Based Payment. This statement requires that the fair value of stock-based awards be measured at the grant date, recognized as compensation expense over the defined service period, and be adjusted for anticipated forfeitures. We estimate the fair value of each stock-based award on the date of grant using a stock option valuation model. The valuation model incorporates assumptions for stock price volatility, the expected exercise period, risk-free interest rate and dividend yield. Some of these assumptions are subjective and require the exercise of judgment. Additionally we must estimate the number of grants that may be forfeited. If actual experience differs significantly from our estimates, compensation expense that we record in future periods may differ materially from that recorded in the current period and that amount projected for future periods.

Internal Accounting Controls

During the course of the audit of our 2005 financial statements, Miller Wachman LLP, our auditors, brought to the attention of our management several weaknesses and reportable conditions that represented significant deficiencies in the design and operation of internal controls, which may have adversely affected Lightspace’s ability to initiate, record, process and report financial data. We have taken the following corrective steps that we believe adequately addressed these deficiencies.

The weaknesses and reportable conditions in our system of internal controls occurred during the approximate period from March 2005 through August and September 2005. During this period, due to the cash situation at Lightspace, we operated without any accounting or finance employees. Only entries affecting cash balances were posted to the financial records, and consequently, no meaningful interim financial statements were prepared. In August and September 2005, we hired accounting consultants to post the transactions for this period and to prepare quarterly and year-to-date financial statements. In October 2005, we signed a contract for a full time CFO and hired an office manager/accountant. Since September 2005, we have produced timely monthly financial statements, forecasts and budget comparisons.

BUSINESS

The following section should be read in connection with our summary historical financial information beginning on pages 14 and 20, the “Use of Proceeds” beginning on page 12 and our financial statements and related notes beginning on page F-1 of this Prospectus. This description of our business contains forward-looking statements that involve risks, uncertainties and assumptions. Our actual results may differ substantially from those anticipated in any forward-looking statements included in this discussion as a result of various factors, including those set forth in “Risk Factors” beginning on page 4 and elsewhere in this Prospectus.

Corporate Overview

Lightspace was formed as a Delaware corporation on August 13, 2001. Our principal business is researching, designing, developing, marketing and selling immersive, interactive environments, called “Lightspace” systems, comprised of patent pending hardware and software technologies designed and developed by us that integrate light, sound and movement. Since our formation, our principal activities have consisted of product research, design and development, market research, business planning, marketing, sales, and distribution of our products.

Technology

The core component of the Lightspace product set is a pressure-sensitive, display panel technology that converts everyday surfaces such as floors, walls, bar tops, tabletops and ceilings into customizable, adaptable, interactive display, gaming, fitness or educational platforms. Through the integration of light, sound and movement, Lightspace technology enables an infinite number of patron-driven experiences for businesses that entertain and engage people.

Our product development strategy is focused on increasing product functionality and in reducing product cost. The current version of the product consists of interactive tiles which use a four-inch by four-inch pixel size. The tiles display millions of discrete colors using Red-Green-Blue light emitting diodes (RGB LEDs), are pressure sensitive and are interconnected via a network. In addition to the tiles, the product is deployed with a control station which controls the interactive tiles over the network connections and a vinyl covering to protect electronics in the tiles from exposure to liquids.

Part of our product development process has focused on reducing the cost of the current tile design over time. In the year ended December 31, 2006, we reduced the cost to manufacture each tile by approximately 17%. We anticipate that additional measures, including overseas manufacturing, new product designs and higher volume production may produce further cost reductions.

Lightspace Interactive System. The Lightspace Interactive Surface (“LIS”) consists of the interactive Lightspace tile system, the Lightspace control station and the Lightspace Management System (“LMS”) which includes software, games and effects packages. The LIS can display lights, effects, images, logos and video in response to the location and movement of participants within its perimeter. The LIS can integrate with existing products and technologies such as sound boards, lighting consoles, display devices (TV screens, projectors, etc.), video servers and industry standard protocols, such as Digital Multiplexing (“DMX”) and Musical Instrument Digital Interface (“MIDI”).

Lightspace Tiles. Lightspace tiles are software driven, LED illuminated and interactive. The tiles can be installed on floors, walls, ceilings and other surfaces such as bar tops and dance cubes. Tiles can be mounted in both surface and recessed configurations and may be interactive or static. Each interactive tile is an individually addressable node, driven by the Lightspace control station and management software via physical network connections.

The dimensions of each tile are 16-inches by 16-inches horizontally and two-and-a-half inches vertically. The horizontal surface of each tile consists of 16 individual four-inch by four-inch pixels displaying millions of discrete colors by using color matched RGB LEDs. Multiple tiles are mounted in an array to create the Lightspace interactive surface. The tiles are manufactured from high-strength polycarbonate, allowing each tile to withstand 3000 pounds of load. Power is distributed from tile to tile via a fault tolerant distribution array. One power supply can support up to one hundred (100) tiles with the ability to connect power supplies in parallel for installations of larger sizes.

Lightspace Control Station with Lightspace Management System (“LMS”). The Lightspace Control Station with LMS is an integrated hardware/software product that creates, stores and plays interactive and non-interactive “Lightsofts” (programmed light effects), “Lightshows” (programmed combinations of Lightsofts) and games on the LIS. The LMS is comprised of the Visual Display Interface (“VDI”), allowing the user to control and change Lightsofts at will by manipulating customization parameters, and the Lightsoft Creator and Lightshow Creator software that collectively facilitate the management, creation and control of Lightsofts and Lightshows. The system can run both manually and automatically, providing users with complete control and versatility. In addition to the visual features described above, the LMS has several diagnostic tools that verify functionality and calibrate the LIS.

Markets

Lightspace systems are designed to serve a wide variety of markets in many applications, such as: “smart surface” sports training, interactive dance floors, guided navigation through public spaces, “smart rooms,” video games built into walls and floors played through movement of the whole body (“exergaming” or “exertainment”), combining education with physical activity (“edutainment”), sports arena surfaces, military or other training simulations and Las Vegas-style gaming.

Our current customers are in the markets of family entertainment centers, child care and fitness centers, retail stores, special event agencies, nightclubs and high-end home consumers. Further markets under development or consideration in the near term include location-based entertainment, trade show exhibits and designs, architects and designers, museums and science centers.

Initial Markets Already Entered

Family Entertainment Centers. Family entertainment centers (“FECs”) are leisure facilities encompassing multiple anchor attractions, offering activities from bowling, video games and miniature golf to go-karts, batting cages and skating rinks. FECs may range in size from small indoor play facilities for young children to multiple-acre facilities offering indoor and outdoor activities for participants of all ages. In 2003, there were approximately 10,000 FECs worldwide, with 8,100 located in the United States. We specifically developed Lightspace Play, a suite of interactive games for the LIS, to address this market.

Rental Agencies. The rental industry can be subdivided into party and special event rentals and advertising, promotional and trade show services.

The party and special event rental sector services high-end bar/bat mitzvahs, birthday parties, children’s events, weddings, fund-raisers and other family or community events. In addition to revenue gained through purchases of Lightspace systems by small businesses operating in this sector, we anticipate that revenue may also be generated through system upgrades, maintenance contracts, and new software content packages.

The advertising, promotional and trade show services sector includes high-end public and corporate promotional event planners. The scale of both the businesses operating in this sector and the events themselves tend to be significantly larger when compared to the party and special events rental sector. Lightspace believes that our products can continue to be sold or leased to numerous event planners to be used at various high-end corporate and private events. Due to the nature of these events, extremely large floors and custom applications are often required, which offer the potential for high sales and rental prices.

Nightclubs. According to Dun & Bradstreet, there are 5,373 drinking establishments in the United States that are designated as nightclubs and discotheques, where the primary entertainment activity is dancing. Additionally, there are approximately 8,500 lounges and clubs where dancing takes place but is not the primary entertainment activity of the establishment. Using LED and pressure sensing technologies, Lightspace Dance was developed specifically to provide a unique interactive product for this market.

Marketing and Sales

Lightspace actively markets its interactive lighting and entertainment products to industries including family entertainment centers, child care and fitness centers, special events, interior and architectural design and nightclubs. Lightspace systems are sold in standard sizes ranging in price from $24,000 to $65,000 and custom designed installations many times larger or smaller, with a price point determined by the size and customization work required for each installation. A limited amount of marketing has been done to date due to very tight budget restrictions and has consisted primarily of trade shows and internet advertising. Sales are conducted through a combination of internal sales people, external sales representatives and limited dealership channels. We have established relationships with third party shipping and logistics firms to enable rapid, low-cost distribution of our product to customer sites.

Lightspace Interactive Surfaces are currently divided into three specific product lines:

(a) Lightspace Play is a gaming system that creates a unique interactive gaming platform that combines lighting and interactive technologies to produce a recreational experience for children and adults;

(b) Lightspace Dance enhances the club experience by offering interactive dance floors, dance cubes, bar tops or runways and walls that respond to club goers movements upon the surface; and

(c) Lightspace Design is an illuminated, interactive tile system displaying customizable light and video effects that can be mounted on practically any flat surface and used for a variety of purposes.

In the fourth quarter of 2006, Lightspace launched a redesigned corporate Web site highlighting the division of the product lines and meeting the obligations imposed on publicly traded companies. Additionally, each product line will have its own micro-site catering to its specific audience utilizing targeted messaging, branding, advertising and images. We anticipate that these micro-sites will be launched in the third quarter of 2007.

We anticipate that a significant amount of our 2007 marketing budget, excluding personnel costs, will be spent on tradeshows, with approximately 80% of our sales coming directly or indirectly from those tradeshows. Six primary tradeshows have been selected for 2007 that target key potential clientele within our current markets. In the fourth quarter of 2006, we purchased a new tradeshow booth and modified our design and fabrication. The remainder of the marketing budget will be distributed between internet advertising, marketing materials and collateral, photo shoots, video shoots, public relations and other marketing costs.

For the year ended December 31, 2006, sales of our products and recognition of other revenue were made to customers in the United States, $567,827, to customers in Asia, $141,851, and to customers in other international countries, $138,523. For the year ended December 31, 2005, sales of our products and recognition of other revenue were made to customers in the United States, $748,800, to customers in Asia, $114,675, to a Canadian customer, $121,750, and to customers in other international countries, $40,381. All 2004 product sales were made to customers in the United States.

The Company had thirteen different customers that each comprised more than 10% of product sales through the three years ended December 31, 2006 and the quarter ended March 31, 2007. In each of the years ended December 31, 2004 and 2005, the Company had four different customers that accounted for $346,318, or approximately 91%, and $668,782, or approximately 68%, respectively, of total product sales. In the year ended December 31, 2006, two customers accounted for $367,851, or approximately 47% of total product sales. In the quarter ended March 31, 2007, three customers accounted for $126,334, or approximately 40% of total product sales. In the quarter ended March 31, 2006, one customer accounted for $24,905, or 100% of total product sales. The Company believes that the high percentage of product sales in each of the aforementioned periods to a small number of customers is the result of the low number of sales and the large dollar values of certain sales and is expected at this point of the Company’s operating history.

Competition

We believe that Lightspace is the first company to develop and offer modularized, illuminated, display surfaces for floors, walls, tabletops and ceilings that are adaptable, pressure sensitive and responsive to human touch. Other companies offer LED display panel technology products or interactive environments using alternative approaches to ours. For example, Element Labs, Inc. currently sells a non-interactive display tile and Reactrix Systems, Inc. currently sells an interactive environment using a projection and camera-based system of limited size. However, we are not aware of any commercial products similar to Lightspace interactive tiles.

Research and Development

During the 2006 fiscal year we continued to invest in our research and development efforts. By applying our research and development across all our products and markets, our strategy is to develop cost-effective interactive tiles and rapidly bring them to market. Our next generation product development is leveraging new technological changes in our industry and in the markets in which we sell our products. Our next generation product line, available in the second quarter of 2007, has a variety of new state-of-the-art capabilities and enhancements in hardware, software, mechanical, and optical components.

Moreover, the development of new products has required, and will require, that we expand our engineering team by additional engineering staff and by hiring subcontractors and consultants to leverage their specific expertise. We anticipate spending $286,000 in fiscal 2007, in addition to staff salaries, in research and development in connection with our efforts to expand and improve our product offerings.

Technology Acquisition

On April 30, 2007, LEC completed the acquisition of the emagipix technology. In connection with the acquisition, the developer of the emagipix technology (a former officer and co-founder of Lightspace Corporation and the principal owner of Illumination Design Works, Inc.), re-commenced employment with Lightspace.

Manufacturing

Lightspace has made a strategic decision to outsource its manufacturing and depends upon a network of vendors, custom parts suppliers, and contract manufacturers to produce its products. We intend to monitor the cost-effectiveness of our vendor network and, when possible, streamline our supply chain to reduce cost, identify and establish relationships with second and third sources for critical materials and services, and ensure ready availability for increasing demand.

Product Warranty and Return Policy

Lightspace provides a limited warranty to all customers for a period of one year from the date of acceptance. Lightspace warrants that the unaltered products will substantially conform to the applicable specifications. During the warranty period, products may be returned for service under our established RMA process and procedures. Pursuant to our warranty, Lightspace’s sole and exclusive liability is, at Lightspace’s option, to repair, replace, or refund the fees paid for the defective products.

Intellectual Property

Lightspace has filed for a number of domestic and international patents covering core aspects of our technology, all of which are currently pending. We have received trademark protection in the United States for the mark “Lightspace,” and endeavor to develop goodwill in this mark as we market and sell our products. We also rely on copyright laws to protect computer programs relating to our Web sites and our proprietary technologies, although to date we have not registered for copyright protection. We have registered Internet domain names related to our business in order to protect our proprietary interests. We also enter into confidentiality and invention assignment agreements with our employees and consultants and confidentiality agreements with other third parties, and we actively monitor access to our proprietary technology.

Governmental Regulation and Certification

To the best of our knowledge, we believe that we are complying with United States regulations concerning lighting, video and sound systems.

Personnel

We currently employ 20 persons on a full-time basis. On March 31, 2006, our Chief Executive Officer (“CEO”) resigned and Gary Florindo, previously our Vice President of Sales and a member of our Board of Directors, was appointed CEO. On February 15, 2007 our Chief Financial Officer resigned. On April 30, 2007, we hired Louis Nunes as Vice President and Chief Financial Officer. We also recently lost senior engineering personnel. We are in the process of interviewing candidates for these positions. We believe that our employee relations are good. We intend to continue to conduct our business primarily using employees and, in some instances, consultants. We anticipate that we will expand our workforce during 2007, including the addition of up to nine employees in our operating and administration departments.

Facilities

Lightspace previously occupied approximately 12,000 square feet of space in Cambridge Massachusetts for office and research and development and assembly and testing of Lightspace systems prior to delivery. Our office lease expired on March 1, 2006. On May 1, 2006, we occupied approximately 16,000 square feet of space in Boston, Massachusetts that we expect will accommodate our present needs and future growth.

Litigation

During the normal course of business, we may at times be involved in disputes and/or litigation with respect to our products, operations or employees. We are not currently involved in any significant litigation.

We currently have no employment agreements with members of our management team. On April 21, 2006, we entered into a severance agreement with Andrew Kennedy Lang, a stockholder, a former director and our former Chief Executive Officer, pursuant to which he resigned as an officer, director and employee of Lightspace. Mr. Lang resigned rather than accept a decrease in salary requested by our board of directors. Under the agreement, we (i) paid him his accrued wages and vacation pay, (ii) reimbursed him for expense incurred on behalf of Lightspace aggregating $47,636, (iii) paid him $10,000 as severance and (iv) paid him $20,000 as advance payment for 100 hours of consulting work.

Total		1,820,490	$	0.80		351,812

In September 2005, our stockholders and Board of Directors approved adoption of our 2005 Stock Plan. The plan provides that the Board of Directors may grant up to 72,080 incentive stock options and/or nonqualified stock options to directors, officers, key employees and consultants. The plan provides that the exercise price of each option must be at least equal to the fair market value of the common stock at the date such option is granted. For grants to individuals who own more than 10% of the outstanding common stock of Lightspace, the exercise price must be at least 110% of fair market value at the time of grant. Options granted under the plan expire within 10 years or less from the date of grant and vest over a period not to exceed four years. At December 31, 2006, we have reserved 53,680 shares of common stock for issuance under the plan upon exercise of outstanding options. Effective with the approval and adoption of the 2006 Stock Plan in June 2006, no additional options can be issued under the 2005 Stock Plan.

On June 9, 2006, our stockholders and Board of Directors approved adoption of our 2006 Stock Plan. The plan provides that the Board of Directors may grant up to 2,118,622 incentive stock options and/or nonqualified stock options to directors, officers, key employees and consultants. The plan provides that the exercise price of each option must be at least equal to the fair market value of the common stock at the date such option is granted. For grants to individuals who own more than 10% of the outstanding common stock of Lightspace, the exercise price must be at least 110% of fair market value at the time of grant. Options granted under the plan expire within ten years or less from the date of grant and vest over a period not to exceed three years. As of December 31, 2006, we have reserved 2,118,622 shares of common stock for issuance under the 2006 Stock Plan upon the exercise of outstanding options.

Options Granted in the 2006 Year

The following table sets forth information with respect to options that we granted to the executive officers named in the Executive Compensation Table during the year ended December 31, 2006.

			Percentage
	Shares		of Total			Exercise				Grant Date
	Underlying		Options			Price				Fair
Executive Officer	Options		Granted (1)			Per Share (2)		Expiration Date		Value (3)
Gary Florindo		423,724		23.1	%	$	0.80		July 3, 2016	$	122,880

James C. Louney (4)		317,793		17.3	%	$	0.80		July 3, 2016	$	92,160

(1) Percentages are calculated based upon a total of 1,836,810 options granted in the year ended December 31, 2006.

(2) All options were granted at fair market value at the time of grant. Grant date fair market value was determined by reference to the proposed public offering price of our units, $6.40, as indicated on our Registration Statement on Form S-1 as filed with the Securities and Exchange Commission at that date, without assigning any value to the unit warrants associated with a unit. Each unit consists of: (1) eight shares of common stock; (2) eight warrants to purchase a total of eight shares of common stock at an exercise price of $1.00 per warrant; (3) two warrants to purchase a total of two shares of common stock at an exercise price of $1.25 per warrant; and (4) two warrants to purchase a total of two shares of common stock at an exercise price of $1.63 per warrant.

(3) The fair value of stock options at the date of grant was determined under the Black-Scholes option pricing model, less the amount that the officer is required to pay upon exercise of the options. The assumptions utilized to calculate fair value for the stock options granted in 2006 are as follows: volatility - 57%; estimated option exercise period - 2 to 3 years; risk free interest rate - 5.14% to 5.17%; and expected total forfeitures of 6.9%.

(4) Upon his resignation on February 15, 2007, Mr. Louney forfeited all options.

Aggregate Option Exercises in 2006 and Value of Options at December 31, 2006

The following table sets forth information with respect to options that were (1) exercised during the year ended December 31, 2006 and (2) that remained unexercised at December 31, 2006 for the executive officers named in the Executive Compensation Table.

	Year 2006				At December 31, 2006
	Shares				Number of		Number of		Value of		Value of
	Acquired		Value		Options		Options		Options		Options
Name	On Exercise #		Realized ($)		Exercisable		Unexercisable		Exercisable		Unexercisable
Gary Florindo		-		-		12,795		425,299	$	2,175	$	85,013

James C. Louney		-		-		-		317,793		-	$	63,559

The value of options exercisable and unexercisable at December 31, 2006 includes only options In-the-Money. Since the date of our initial public offering, November 2, 2006, through December 31, 2006, only our units have traded on the OTC Bulletin Board. The closing sale price for our unit security as reported on the OTC Bulletin Board was $8.00. Each unit consists of: (1) eight shares of common stock; (2) eight warrants to purchase a total of eight shares of common stock at an exercise price of $1.00 per warrant; (3) two warrants to purchase a total of two shares of common stock at an exercise price of $1.25 per warrant; and (4) two warrants to purchase a total of two shares of common stock at an exercise price of $1.63 per warrant. If no value is assigned to the unit warrants, the eight shares of common stock would be value at $8.00, or $1.00 per share. The value of executive officer options has been calculated on the basis as the difference between $1.00 and the exercise price of the option, multiplied by the number common shares underlying the option. Upon his resignation on February 15, 2007, Mr. Louney forfeited all options.

Director Liability and Indemnification

Under Delaware law and our by-laws, we are required to indemnify our officers, directors, employees and agents in certain situations. As permitted by Delaware statutes, our certificate of incorporation eliminates in certain circumstances the monetary liability of our directors for a breach of their fiduciary duties. These provisions do not eliminate a director’s liability for:

Any breach of the director’s duty of loyalty to the corporation or its stockholders

Acts or omissions not in good faith or which involve intentional misconduct or knowing violation of law

Under Section 174 of Title 8 of the Delaware code

Any transaction from which the director derived an improper personal benefit

As to indemnification for liabilities arising under the Securities Act for directors, officers or persons controlling Lightspace, we have been informed that, in the opinion of the Securities and Exchange Commission, such indemnification is against public policy and therefore unenforceable.

SELLING SECURITYHOLDERS

The following table sets forth the names of the Selling Securityholders who may sell their securities under this Prospectus from time to time. No Selling Securityholder has, or within the past three years has had, any position, office or other material relationship with us or any of our predecessors or affiliates other than as a result of the ownership of our securities, except for David Hoch, who was an officer and director from 2001 to June, 2005, and recently rejoined as Chief Scientist.

The following table also provides certain information with respect to the Selling Securityholders’ ownership of our securities as of May 31, 2007, the total number of securities they may sell under this Prospectus from time to time, and the number of securities they will own thereafter assuming no other acquisitions or dispositions of our securities. The Selling Securityholders can offer all, some or none of their securities, thus we have no way of determining the number they will hold after this offering. Therefore, we have prepared the table below on the assumption that the Selling Securityholders will sell all shares covered by this Prospectus.

Some of the Selling Securityholders may distribute their securities, from time to time, to their limited and/or general partners or managers, who may sell securities pursuant to this Prospectus. Each Selling Securityholder may also transfer securities owned by him or her by gift, and upon any such transfer the donee would have the same right of sale as the Selling Securityholder.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

The following transactions were or will be entered into with our executive officers, directors and 5% or greater stockholders. These transactions may or will continue in effect and may result in conflicts of interest between us and these individuals. Although our executive officers and directors have fiduciary duties to us and our stockholders, we cannot assure that these conflicts of interest will always be resolved in our favor or in the favor of our stockholders.

April 30, 2007 Private Placement

On April 30, 2007 we sold in a private placement to certain investors (the “April 30, 2007 Private Investors”) 586,173 Units at the offering price of $6.40 per Unit, resulting in aggregate proceeds to Lightspace of $3,751,507. After estimated expenses of the offering of $311,507, the net proceeds to Lightspace were approximately $3,440,000. The sale of 586,173 Units resulted in the issuance of (1) 4,689,384 shares of common stock; (2) 4,689,384 Unit Warrants to purchase a total of 4,689,384 shares of common stock at an exercise price of $1.00 per Warrant; (3) 1,172,346 Unit Warrants to purchase a total of 1,172,346 shares of common stock at an exercise price of $1.25 per Warrant; and (4) 1,172,346 Unit Warrants to purchase a total of 1,172,346 shares of common stock at an exercise price of $1.63 per Warrant. The Unit Warrants are exercisable at the option of the holder at any time up until April 30, 2012, at which date the Unit Warrants expire. In the event of a division of our common stock, the Unit Warrants will be adjusted proportionately. Lightspace has entered into a Registration Rights Agreement with the purchasers of the Units, whereby we have agreed to file a registration statement to register for resale the shares of common stock, Unit Warrants and shares of common stock issuable upon exercise of the Unit Warrants, included in the Units issued in the private placement to the April 30, 2007 Private Investors and issuable upon exercise of the Griffin Warrant.

In connection with the sale of the equity units, Lightspace paid Griffin, the financial advisor for the private placement, a fee in the amount of $187,575 and issued to Griffin the Griffin Warrants, exercisable to purchase up to 58,617 Units, in the same form sold in the private placement, at an exercise price of $6.40 per Unit.

The April 30, 2007 Private Placement Investors included AIGH, Amtrust International Insurance Ltd., South Ferry Building Company, Herschel Berkowitz, Asia Marketing, LaPlace Group LLC and Ellis International, major stockholders of the Company, who purchased 125,000, 143,940, 39,062, 45,000, 6,250, 15,625 and 42,968 Units respectively.

Emagipix Technology Acquisition

On March 29, 2007, Lightspace Emagipix Corporation (“LEC”), a newly formed wholly-owned subsidiary of Lightspace Corporation, entered into an agreement with Illumination Design Works, Inc. to acquire the in process development technology emagipix, an interactive lighting technology that utilizes electroluminescent sheets. The purchase price for the emagipix technology consisted of an initial cash payment of $45,000 upon signing the agreement and a cash payment of $255,000 and the issuance of a $950,000 convertible secured non-recourse note (the “Convertible Note”) to Illumination Design Works, Inc. upon the closing of the technology purchase. On April 30, 2007, LEC completed the acquisition of the emagipix technology. In connection with the acquisition, the developer of the emagipix technology (a former officer and co-founder of Lightspace Corporation and the principal owner of Illumination Design Works, Inc.), re-commenced employment with Lightspace.

The Convertible Note bears interest a 5% per annum, payable yearly, and is due and payable on April 30, 2011. The Convertible Note is secured by a pledge of 67% the stock of LEC. The principal of the note is convertible at any time up and until April 30, 2011, at the option of the holder, into the common stock of Lightspace Corporation at a conversion price of $0.80 per share. Upon the occurrence of certain defined events of default by the noteholder, Lightspace has the right to convert the Convertible Note to common stock at the lower of the conversion price of $0.80 or the then current market price of the common stock.

Exchange Agreement

On February 9, 2006, we entered into the Exchange Agreement with (1) holders of $1,401,000 in principal amount of convertible notes and $1,538,234 in principal amount of demand notes, (2) holders of 133,732 shares of Series A convertible preferred stock and (3) existing warrantholders to provide for the terms of the debt conversion, preferred conversion and warrant exchange. On April 27, 2006, the conditions for the closing of the Agreement having been met, Lightspace effected the conversion and exchange. Under the terms of the Agreement, (1) the holders of convertible and demand notes received 1,544,865 shares of common stock and exchange warrants to purchase 1,480,849 shares of common stock at exercise prices ranging from $0.80 to $7.50 per share upon conversion of their existing notes and any warrants issued in conjunction therewith, and our former CEO received a contingent promissory note in the principal amount of $237,381; (2) the holders of Series A convertible preferred stock received 160,479 shares of common stock upon conversion of their Series A convertible preferred stock; and (3) the holders of other existing warrants received exchange warrants to purchase 41,063 shares of common stock at an exercise price of $7.50 per share. As a result of the closing of the Agreement, we recorded a one-time non cash net gain of $402,298.

Debt Conversion

Pursuant to the Exchange Agreement, the $1,401,000 in principal amount of convertible notes and accrued interest due thereon were converted into 676,333 shares of common stock and exchange warrants to purchase 108,534 shares of common stock, including exchange warrants to purchase 32,780 shares of common stock issued upon the conversion of the outstanding warrants to purchase Series A preferred stock. The original stipulated conversion ratios of the convertible notes, which ranged from $1.75 to $17.25, were renegotiated to range from $0.85 to $5.00. The original conversion ratios would have resulted in the issuance of 345,797 shares of common stock and the warrants originally issued in conjunction with certain of the convertible notes would have required Lightspace to issue an aggregate of 75,266 shares of common stock at exercise prices ranging from $12.50 to $25.63 per share. The exchange warrants issued to the holders of convertible notes have an exercise price of $7.50 per share and expire on April 30, 2011.

Also pursuant to the Exchange Agreement, $1,538,234 in principal amount demand notes and accrued interest due thereon were converted into 868,532 shares of common stock and exchange warrants to purchase 1,011,063 shares of common stock, except for $237,381 in principal amount of the demand notes which were exchanged for the “Lang Note” as described below. Pursuant to the Agreement, the demand notes were converted at negotiated rates ranging from $0.85 to $3.00. The exchange warrants issued to holders of the demand notes have exercise prices that range from $0.80 to $7.50 per share and expire on April 30, 2011.

As part of the debt conversion, Mr. Lang, our former Chief Executive Officer, and L Ventures, his affiliate, were issued (a) 641,063 shares of common stock, (b) warrants to purchase 819,741 shares of common stock at exercise prices ranging from $0.80 to $3.00 and (c) a contingent promissory note in the principal face amount of $237,381, more fully described under “Lang Note” below, upon the conversion of an aggregate of $887,636 in principal amount of convertible and demand notes, plus all accrued interest thereon, held by Mr. Lang and L Ventures. Mr. Tandon, a major stockholder, was issued (a) 500,949 shares of common stock and (b) warrants to purchase 356,748 shares of common stock at exercise prices ranging from $3.00 to $7.50 upon the conversion of $1,076,000 in principal face amount, plus all accrued interest thereon, of convertible notes.

Preferred Conversion

In December 2003 and the third and fourth quarters of 2004, Lightspace sold 100,000 and 33,732 shares, respectively, of its Series A preferred stock for $1,025,000 and $345,754, respectively, in private placements to unrelated investors (with the exception of Mr. Tandon, who purchased 124,390 shares of Series A preferred stock). Pursuant to the Exchange Agreement, all shares of the Series A preferred stock were converted into 160,479 shares of common stock. The original stipulated conversion ratio of the Series A preferred stock, one share of common stock for one share of Series A preferred stock (or 0.4 share of common stock for one share of Series A preferred stock after giving effect to the one for 2.5 reverse stock split), was renegotiated and modified to provide a conversion ratio of three shares of common stock for one share of Series A preferred stock. Mr. Tandon received 149,268 shares of common stock upon the conversion of 49,756 shares of Series A preferred stock.

Immersive Promotions

In the second quarter of 2005, we entered into a series of transactions with Immersive Promotions (“Immersive”), an affiliate of Mr. Lang, our former CEO, wherein we sold to Immersive 315 interactive tiles and other Lightspace systems components for $219,718. Immersive was established as a rental and events company with Mr. Lang as a significant investor. Lightspace had previously determined that due to limited capital, our business objectives, and the potential of conflict with our current rental and promotional customers, we would not directly engage in the retail business segment of events and promotions. The transactions with Immersive were completed by a cash payment from Immersive of $110,000 and the transfer to Immersive and cancellation of $109,718 in principal amount of demand notes due to Mr. Lang.

Immersive’s first possible promotional event was several months in the future. In the interim, we had several potential customers, but had exhausted the available inventory of interactive tiles. We agreed with Immersive to unwind the sale to Immersive and take back the unused 315 interactive tiles and other Lightspace systems components. We paid back to Immersive $147,333 in cash, leaving a balance due to Immersive of $72,385. As part of the April 21, 2006 severance agreement with Mr. Lang, described below, we paid Immersive $20,000, and agreed to use our best efforts to pay the $52,385 balance due by December 31, 2006. The $52,385 balance due to Immersive remains unpaid at June 15, 2007. We intend to repay the obligation to Immersive when we generate sufficient revenues to make such payment.

On April 21, 2006, we entered into a severance agreement with Mr. Lang, a stockholder, a former director and our former Chief Executive Officer, pursuant to which he resigned as an officer, director and employee of Lightspace. Under the agreement, we (i) paid him his accrued wages and vacation pay, (ii) reimbursed him for recorded expenses incurred on behalf of Lightspace aggregating $47,636, (iii) paid him $10,000 as severance and (iv) paid him $20,000 as advance payment for 100 hours of consulting work. We also paid $20,000 against the accounts payable balance incurred in the transaction with Immersive Productions described above.

Lang Note

In connection with the Exchange Agreement, $237,381 in principal amount of demand notes held by Mr. Lang, formerly our CEO and a director and currently a principal stockholder of Lightspace, were converted into a $237,381 contingent promissory note. The note bears interest at an annual rate of 8% and is payable by us only if we achieve two consecutive quarters of positive EBITDA (i.e., earnings before interest, taxes, depreciation and amortization), aggregating at least $1,000,000, or we raise in a registered public offering of equity cash proceeds of at least $10 million prior to December 31, 2008. If those conditions are not met by December 31, 2008, or Mr. Lang is found to be in breach of the terms of his Severance Agreement prior to such date, the note will not be payable. In addition, Lightspace issued to Mr. Lang exchange warrants to purchase 361,252 shares of common stock at an exercise price of $0.80 per share. The warrants expire on April 20, 2011, unless the terms for payment of the note are not met, in which case the warrants will expire on March 31, 2009.

DESCRIPTION OF SECURITIES

General

Our certificate of incorporation provides that we are authorized to issue up to 75,000,000 shares of stock common stock, par value $0.0001 per share. As of June 20, 2007, we had 15,282,495 shares of common stock issued and outstanding and held of record by approximately 85 stockholders. The shares of our previously authorized Series A Preferred Stock were surrendered and cancelled pursuant to the Exchange and we have revised our certificate of incorporation to remove authorization for the issuance of preferred stock. We also had issued options to purchase 1,718,685 shares of common stock, warrants to purchase 23,634,205 shares of common stock and a $950,000 Note convertible into 1,187,500 shares of common stock. Our certificate of incorporation allows our board of directors to issue shares of common stock up to the total amount of authorized shares without obtaining the prior approval of stockholders.

The following description of our common stock and warrants summarizes the material provisions of each and is qualified in its entirety by the provisions of our certificate of incorporation, bylaws and warrant agreements, copies of which have been filed as exhibits to our registration statement on Form S-1, of which this Prospectus is a part, filed with the Securities and Exchange Commission. See “Where You Can Find More Information” on page 57.

Common Stock

As holders of our outstanding common stock, in general your rights and privileges will be as follows:

the right to one vote for each share held of record on all matters submitted to a vote of the stockholders, including the election of directors,

no cumulative voting rights, which means that holders of a majority of shares outstanding can elect all of our directors,

the right to receive ratably dividends when, if and as may be declared by our board of directors out of funds legally available for such purposes, subject to the senior rights of any holders of preferred stock then outstanding (if any),

the right to share ratably in the net assets legally available for distribution to common stockholders after the payment of our liabilities and preferred stock liquidation preferences on our liquidation, dissolution and winding-up,

in the event a compromise or arrangement is proposed between Lightspace and its creditors or stockholders, or a class of its creditors or stockholders, upon the application of a party in interest, a court may order that a meeting of the relevant group of creditors or stockholders be held, and the approval of three-fourths in value of the creditors or class of creditors or three-fourths of the shares held by the stockholders or class of stockholders, of the proposed compromise or arrangement, and any related reorganization of Lightspace, shall be binding on Lightspace, provided the compromise or arrangement is sanctioned by the presiding court, and

no preemptive or conversion rights or other subscription rights, and no redemption privileges.

All outstanding shares of common stock are fully paid and nonassessable.

Unit Warrants and Exchange Warrants

There were 15,282,495 issued and outstanding shares of the Company’s common stock at June 20, 2007. Additionally, there were issued and outstanding at June 20, 2007: (i) 22,112,293 Unit Warrants, including 468,936 $0.80 Unit Warrants, 816,000 $0.96 Unit Warrants, 13,884,905 $1.00 Unit Warrants, 3,471,226 $1.25 Unit Warrants and 3,471,226 $1.63 Unit Warrants, (ii) 1,521,912 Exchange Warrants exercisable to purchase an aggregate of up to 1,521,912 shares of common stock, exercisable at prices that range from $0.80 to $7.50 and (iii) the Convertible Note, convertible into 1,187,500 shares of common stock. Each $.0.80, $.96, $1.00, $1.25 and $1.63 Unit Warrant gives its holder the right to purchase one share of common stock, respectively. The Warrants are or will be exercisable through various dates up to the close of business on April 30, 2012. A maximum of 23,634,205 shares of common stock will be issuable upon the exercise of the Warrants. The Warrants are issued pursuant to the terms of a warrant agreement between the warrant agent, Continental Stock Transfer & Trust Company, and us. We have authorized and reserved for issuance the shares of common stock issuable on the exercise of the Warrants.

The Warrants may be exercised by surrendering the certificate representing the Warrants on or prior to the expiration date at the offices of the warrant agent with the warrant certificate completed and executed as indicated. The warrant exercise price must be paid in full at the time of exercise. Shares of common stock issued upon proper exercise will be fully paid and non-assessable. The exercise price may be paid by cash, check or exercise on a cashless basis. Exercises on a cashless basis enables the holder to exercise the Warrants without paying the cash exercise price of the Warrants. In a cashless exercise, the Warrant holder is able to acquire a number of shares of common stock equal to the inherent value of the Warrants to be exercised (the aggregate fair market value of the common stock that may be acquired upon the exercise of the Warrants minus the total exercise price of the Warrants) divided by the value of the common stock. The “value” of the common stock will be determined using the average of the closing bid and asked prices (or in the event the Company’s securities are listed on Nasdaq Stock Market or an exchange, the last reported sale price) of the common stock for the 30 trading days ending on the day prior to the notice of exercise of the Warrant.

There can be no assurance that the value of the common stock will exceed any of the Warrant exercise prices.

The exercise price of the Warrants and the number of shares of common stock that may be issued when the Warrants are exercised are subject to adjustment if specific events occur, including stock dividends, stock splits, combinations and reclassifications of our common stock.

The Unit Warrants issued in connection with the Company’s initial public offering are not exercisable unless we have a current Prospectus covering the shares of common stock to be issued upon exercise of such Unit Warrants and the shares have been registered, qualified or deemed to be exempt from registration under the securities laws of the state of residence of the exercising holder of the Unit Warrants. Although the law requires and we have agreed to keep a registration statement effective which covers the issuance of the common stock on exercise of the Unit Warrants, if we fail to do so for any reason, the Unit Warrants may not be exercisable and therefore of no value. If the Unit Warrants are not exercisable at their expiration date because a current registration statement for the shares to be issued upon exercise is not available, then the expiration date will be extended until 30 days following notice from us that the Unit Warrants are again exercisable. Nevertheless, there is a possibility that the Unit Warrants will never be exercisable when in-the-money or otherwise, and that holders of Unit Warrants will never receive shares of common stock.

The Warrants do not confer on the warrant holder any voting, dividend or other stockholder rights.

Griffin Warrants

In connection with the sale of the Units in April 30, 2007 Private Placement, Lightspace paid Griffin, the financial advisor for the private placement, a fee in the amount of $187,575 and issued to Griffin the Griffin Warrants, exercisable for 58,617 Units, in the same form sold in the private placement and described above, at an exercise price of $6.40 per Unit.

Underwriter’s Warrant

In connection with our initial public offering, we issued to Griffin Securities, Inc., our underwriter in the offering, warrant, expiring November 4, 2011, exercisable to purchase 102,000 Units at $7.68 per Unit.

Transfer Agent and Registrar

We appointed Continental Stock Transfer & Trust Company, New York, New York, as transfer agent and registrar of our Units, common stock and Warrants. The mailing address of Continental Stock Transfer & Trust Company is Two Broadway, New York, New York 10004.

Listing of Units, Common Stock and Warrants

Our securities currently trade on the OTC Bulletin Board. Our securities are not listed on any securities exchange or on the NASDAQ stock market, and we will not apply for such a listing. We do not intend to register our securities pursuant to Section 12 of the Exchange Act. As a result, the available information about us may be less than the amount of information usually associated with a public company, further restricting the market for our securities. We cannot guarantee that our common stock or Unit Warrants will continue to trade on the OTC Bulletin Board or any other exchange or quotation medium. Even if listed for trading, there may still be no market for our Units, common stock or Unit Warrants.

Stockholder Action

Under our bylaws, the affirmative vote of the holders of a majority of the shares of common stock represented at a meeting at which a quorum is present is sufficient to authorize, ratify or consent to any action required by the common stockholders, except as otherwise provided by the Delaware General Corporation Law. Under the Delaware General Corporation Law and our bylaws, our stockholders may also take actions by written consent without holding a meeting. The written consent must be signed by the holders of at least a majority of the voting power, except that if a different proportion of voting power is required for a specific action, then by holders holding that proportion. If this occurs, we are required to provide prompt notice of any corporate action taken without a meeting to our stockholders who did not consent in writing to the action.

SHARES ELIGIBLE FOR FUTURE SALE

We cannot predict the effect, if any, that market sales of shares of our common stock or Unit Warrants or the availability of shares of common stock or Unit Warrants for sale will have on the market price of our Units, common stock or Unit Warrants prevailing from time to time. Nevertheless, sales of substantial amounts of our common stock or Unit Warrants in the public market could adversely affect the market price of our securities and could impair our future ability to raise capital through the sale of equity securities. There are a significant number of shares of common stock and Unit Warrants eligible for future sale and this may hurt the market price of our securities.

Future Sale of Shares

We have an aggregate of 15,282,495 shares of common stock outstanding. 10,482,495 shares of common stock will be deemed restricted securities as defined under Rule 144. Restricted securities may be sold in the public market only if registered or if they qualify for an exemption from registration under Rules 144, 144(k) or 701 under the Securities Act.

We cannot predict the effect, if any, that the sale of our common stock or the availability of shares of common stock for sale will have on the market price prevailing from time to time. Nevertheless, sales of substantial amounts of common stock in the public market could adversely affect the market price of our common stock and adversely affect our ability to raise capital at times and on terms favorable to us.

Lock-up Agreements with Griffin

Certain stockholders, including employees, directors and officers, who hold an aggregate of 5,793,111 shares of common stock have agreed to not sell or otherwise dispose of any shares of our common stock that they beneficially own for a period ending October 4, 2007 without the prior written consent of Griffin Securities, Inc. (“Griffin”).

Griffin may release all or a portion of the shares held by officers and directors subject to lock-up agreements. Griffin has advised us that any request to release all or any portion of the shares from the lock-up agreements will be considered on a case-by-case basis and depend on several factors including, but not limited to, our stock price, average trading volume, general market conditions, recent financial performance and perceived market reaction. However, Griffin’s decision is in its sole discretion and may not be based on any specific parameters. If any or all of those shares were released by Griffin, such shares would likely be eligible for sale in the public market. Increasing the number of shares available for sale in the public market could cause the price of our stock to decline.

Rule 144

In general, under Rule 144 as currently in effect, a person who has beneficially owned restricted securities for at least one year, including one of our affiliates, would be entitled to sell within any three-month period a number of shares that does not exceed the greater of:

1% of the number of shares of our common stock then outstanding, or

the average weekly trading volume of our common stock during the four calendar weeks preceding the filing of a notice of such sale.

Sales under Rule 144 also are limited by manner-of-sale provisions, notice requirements and requirements relating to the availability of current public information about us.

Rule 144(k)

In general, under Rule 144(k) as currently in effect, a person who is not deemed to have been one of our affiliates at any time during the three months preceding a sale, and who has beneficially owned the shares proposed to be sold for at least two years (including the holding period of any prior owner except one of our affiliates), is entitled to sell these shares without complying with the manner-of-sale, public information, volume limitation or notice provisions of Rule 144 discussed above.

Rule 701

In general, rule 701 permits resale of shares in reliance on Rule 144 but without compliance with some restrictions of Rule 144. Any employee, officer, director or consultant who purchased his shares under a written compensatory plan or contract may rely on the resale provisions of Rule 701. Under Rule 701:

affiliates can sell Rule 701 shares without complying with the holding period requirements of Rule 144,

non-affiliates can sell these shares in reliance on Rule 144 without having to comply with the holding period, public information, volume limitation or notice provisions of Rule 144, and

shares must be held at least 90 days after the date of this Prospectus before they can be resold.

PLAN OF DISTRIBUTION

The Selling Securityholders, including any donee, pledgee, transferee or other successor-in-interest, selling Company securities or interests thereon received after the date of this Prospectus from a Selling Securityholder as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their interests thereon on any stock exchange, market or trading facility on which the securities are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at other negotiated prices.

The Selling Securityholders may use any one or more of the following methods when disposing of Securities or interests therein:

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

block trades in which the broker-dealer will attempt to sell the securities as agent, but may position and resell a portion of the block as principal to facilitate the transaction;

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

an exchange distribution in accordance with the rules of the applicable exchange;

privately negotiated transactions;

short sales effected after the effective date under the Securities Act of the registration statement of which this Prospectus is a part;

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

broker-dealers may agree with the Selling Securityholders to sell a specified number of such securities at a stipulated price;

a combination of any such methods of sale; and

any other method permitted pursuant to applicable law.

The Selling Securityholders may, from time to time, pledge or grant a security interest in some or all of the securities of Common Stock owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the securities, from time to time, under this Prospectus, or under an amendment to this Prospectus under Rule 424(b)(3) under the Securities Act or other applicable provision of the Securities Act amending the list of Selling Securityholders to include the pledgee, transferee or other successors in interest as Selling Securityholders under this Prospectus. The Selling Securityholders also may transfer the securities in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this Prospectus.

In connection with the sale of Common Stock or interests therein, we have been advised by the Selling Securityholders that they may enter into hedging transactions with broker-dealers or other financial institutions, who may in turn engage in short sales of the Common Stock in the course of hedging the positions they assume. The Selling Securityholders may also sell securities short and deliver the Common Stock covered by this Prospectus to close out their short positions, or loan or pledge the Common Stock to broker-dealers who in turn may sell these securities. The Selling Securityholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities that require the delivery to such broker-dealer or other financial institution of securities offered by this Prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this Prospectus (as supplemented or amended to reflect such transaction).

We have advised the Selling Securityholders that, during such time as they may be engaged in a distribution of any of the shares that are the subject of this Prospectus, they are required to comply with Regulation M, as promulgated under the Exchange Act. In general, Regulation M precludes any Selling Securityholder, any affiliated purchaser and any broker-dealer or other person who participates in such distribution, from bidding for or purchasing, or attempting to induce any person to bid for or purchase, any security that is the subject of the distribution until the entire distribution is complete. Regulation M defines a “distribution” as an offering of securities that is distinguished from ordinary trading activities by the magnitude of the offering and the presence of special selling efforts and selling methods. Regulation M also defines a “distribution participant” as an underwriter, prospective underwriter, broker, dealer, or other person who has agreed to participate or who is participating in a distribution. Our officers and directors, along with our affiliates, will not engage in any hedging, short sales, or any other type of transaction covered by Regulation M.

Regulation M prohibits any bids or purchases made in order to stabilize the price of a security in connection with the distribution of that security, except as specifically permitted by Rule 104 of Regulation M. Stabilizing transactions may cause the price of the Securities to be higher than it would otherwise be in the absence of those transactions. We have advised the Selling Securityholders that stabilizing transactions permitted by Regulation M allow bids to Securities so long as the stabilizing bids do not exceed a specified maximum, and that Regulation M specifically prohibits stabilizing that is the result of fraudulent, manipulative, or deceptive practices. Selling Securityholders and distribution participants will be required to consult with their own legal counsel to ensure compliance with Regulation M.

If a Selling Securityholder wishes to enter into a short sale of securities “against the box” and cover the short sale with registered securities after the date of this Prospectus, the short sale may not be consummated before the registration statement of which this Prospectus is a part becomes effective, because the securities underlying the short sale are deemed by the SEC to be sold at the time such short sale is made. We and each Selling Securityholder have confirmed to the SEC that they are aware of the SEC’s Telephone Interpretation A. 65 (July 1997) with respect to short sales.

Expenses of this offering, estimated to be $83,425 other than any discounts, commissions or similar fees charged in connection with the sale of any share of Common Stock offered hereby, will be borne by us.

The Selling Securityholders also may resell all or a portion of the securities in open market transactions in reliance upon Rule 144 under the Securities Act, provided that they meet the criteria and conform to the requirements of that rule.

The Selling Securityholders and any underwriter, broker-dealer or agent that participates in the sale of the securities or interests therein may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions, profit or other compensation any of them earns on any sale or resale of the shares, directly or indirectly, may be underwriting discounts and commissions under the Securities Act. Selling Securityholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the Prospectus delivery requirements of the Securities Act.

We have agreed with the April 2007 Placement Selling Securityholders and Illumination Design Works, Inc. to keep the registration statement of which this Prospectus constitutes a part effective until the earlier of (1) such time as all of the shares covered by this Prospectus have been disposed of pursuant to and in accordance with the registration statement or (2) the date on which the shares may be sold pursuant to Rule 144(k) of the Securities Act, but in no event later than April 30, 2009.

Each Selling Securityholder has represented and warranted to us that, at the time it acquired the securities subject to the registration statement, it did not have any agreement or understanding, directly or indirectly, with any person to distribute any of such securities. We have advised each Selling Securityholder that it may not use securities registered on the registration statement to cover short sales of that Selling Securityholder’s Common Stock made prior to the date on which the registration statement is declared effective by the SEC.

None of our securities included in this Offering may be offered or sold, directly or indirectly, nor may this Prospectus or any other offering material or advertisements in connection with the offer and sales of any of our Units, common stock or Unit Warrants be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction. This Prospectus is neither an offer to sell nor a solicitation of any offer to buy any of our Units, common stock or Unit Warrants included in this Offering in any jurisdiction where that would not be permitted or legal.

Our securities may be considered “penny stock” under a Commission rule that imposes additional sales practice requirements on underwriters and broker-dealers who sell such securities to persons other than established customers and institutional accredited investors (generally institutions with assets in excess of $5 million). For transactions covered by the rule, the underwriter or broker-dealer must make a special suitability determination about the purchaser (which concerns financial and business sophistication previous investment experience and financial condition) and have received the purchaser’s written agreement to the transaction prior to the sale. Such underwriters or broker-dealers must also, prior to such sale, provide the customer with a risk disclosure document which identifies risks associated with investing in “penny stocks” and which describes the market therefor as well as a brief description of the broker-dealer’s obligations under certain “Penny Stock Rules” and rights and remedies available to customers under federal and state securities laws. The broker-dealer must obtain a signed and dated acknowledgment from its customer demonstrating that the customer has actually received the required risk disclosure document before the first transaction in penny stock. Consequently, such rules will affect the ability of the underwriter and any broker-dealers to sell our securities and will affect the ability of purchasers in this Offering to sell their securities in the secondary market, if any.

Report of Independent Registered Public Accounting Firm

To the Stockholders and Board of Directors of Lightspace Corporation

We have audited the accompanying statements of financial position of Lightspace Corporation as of December 31, 2006 and 2005 and the related statements of operations, stockholders’ equity (deficit) and cash flows for each of the years in the three-year period ended December 31, 2006. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company was not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Lightspace Corporation as of December 31, 2006 and 2005 and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2006 in conformity with accounting principles generally accepted in the United States of America.

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Notes 1 and 2 to the financial statements, the Company has had deficiencies in stockholders’ equity and recurring losses and negative cash flows from operations which raise substantial doubt about its ability to continue as a going concern. Management’s plans concerning these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.
