ABSTRACT:
A display device for creating the illusion of a three dimensional image is disclosed. The device includes a generally planar light transmitting surface having both a background image and an intermediate image formed thereon, the foreground image being in focus, the background scene or image being out of focus. A generally planar mirror has a foreground image located thereon and is maintained at an acute angle with respect to the light transmitting surface such that the light transmitting surface may be viewed by looking at the mirror along an axis which is within the acute angle. A light source is provided for projecting light through the light transmitting surface onto the mirror for reflection thereby.
