Greystone Digital Technology, Inc. (Greystone), as of August 6, 2002, has closed all operations and ceased offering any of the software products and supporting engineering services that it had provided to its customers throughout its existence. The Company has operated as a software development and systems integration company since the Company commenced business in 1989. From its founding date the Company concentrated on development of real-time, interactive, and networked three-dimensional visual and aural software needed to create and render simulated virtual environments. The Company offered different applications of its software along with supporting engineering services to customers in government and commercial markets. As a development company, Greystone continued to create new applications but has not been able to make its business grow sufficiently from sales of its applications and supporting services to generate self-sustaining positive cash flow from operations.
