1. A system for providing a dynamic audio-visual environment, comprising:
- a plurality of eSurfaces situated in a room environment;
a projector situated for projecting images onto each eSurface;
a camera situated to picture the room environment;
a central processor coupled to all eSurfaces situated in the room environment, said projector and said camera;
said processor receiving pictures from said camera for detecting location of all eSurfaces situated in the room environment; and
controlling said projector to aim projection beam of said projector onto each eSurface; and
,wherein each eSurface comprises a sheet-like surface having the property of accepting optically projected image when powered, and retaining the projected image after the power is turned off.

Abstract
A system for providing a dynamic audio-visual environment using an eSurface situated in a room environment; a projector situated for projecting images onto the eSurface; a camera situated to picture the room environment; a central processor coupled to the eSurface, the projector and the camera. The processor receives pictures from the camera for detecting the location of the eSurface; and controls the projector to aim its projection beam onto the eSurface. The eSurface is a sheet-like surface having the property of accepting optically projected image when powered, and retaining the projected image after the power is turned off.
