Abstract: A projection system includes a cabinet having a surface with an aperture therein, a projector disposed within the cabinet, adapted to project light through the aperture in the surface of the cabinet, and a lens disposed in the aperture to project the light onto a screen disposed generally non-parallel to the cabinet surface having the aperture.

Abstract: An enhanced-contrast projection screen and method of controlling such screens are disclosed. An embodiment of a dynamic projection screen includes a passive layer and at least one active layer. The active layer is superimposed on at least a portion of the passive layer and is adapted to selectively toggle between being transparent and being opaque. A method of controlling such a screen includes determining desired dimensions of a reflective region, and activating at least a portion of an active layer superimposed on at least a portion of a passive layer. The active layer is adapted to selectively toggle between being transparent and opaque.
