Abstract

An assembly including a substantially transparent front panel and a partially translucent screen with a partially reflective front surface positioned to face a rear side of the front panel and spaced apart therefrom by a predetermined distance. A first image is defined on the rear side for reflection by the front surface to provide a virtual image thereof. A back wall is positioned behind the screen and displays a second image on an exposed surface thereof facing the rear surface of the screen. The exposed surface is spaced apart from the front surface of the screen by the predetermined distance. The virtual image is located substantially in the plane of the exposed surface so that the virtual image appears to be positioned behind the screen.
