Tech demo

A Tech Demo is a computer and video game industry term referring to short applications designed to gauge interest in an upcoming product or to demonstrate hardware-specific features. Tech Demos have various levels of interactivity, ranging from real-time videos to short but fully playable demonstrations. Tech Demos are rarely intended to be turned into fully fledged commercial products, though their ideas and concepts are sometimes reused. Tech Demos are not to be confused with Vaporware, a commercial product which presumably started development but never got released.
