Abstract
An assembly is provided for producing an illusory effect. The assembly comprises a substantially transparent front wall having a rear surface and a front surface. A reflective surface is spaced from and faces the rear surface of the front wall. A plurality of first dots are disposed on the front wall in a sufficiently constant density over a given area to produce a substantially constant tinted appearance to the front wall when observed through the front surface. A plurality of second dots are disposed on the first dots and face the reflective surface, the second dots being smaller than the first dots. An image is defined by the second dots wherein the image is substantially invisible to an observer looking through the front surface other than as a reflected image in the reflective surface.
