Abstract
A screen simulator window having a window aperture through which a scene may be viewed with a partial screen arranged immediately behind the window. The screen consists of alternately opaque screen portions and transparent screen portions. The adjacent screen portions are transposed at a speed such that the presence of the screen is not apparent to the eye of the viewer. A projector projects a scene onto rear sections of the opaque screen portions extending away from the window. A mirror behind the partial screen is viewable through the window. The scene projected onto the rear surface of the opaque screen portions is visible in the mirror and viewable through the window.
