Abstract
An apparatus and method for displaying an anamorphic illusion utilizes two flat disks, each having different unrecognizable images on their top surfaces. A reflecting surface is positioned perpendicular to the disks. A viewer is able to see a recognizable composite reflected image of the two unrecognizable images by looking at the reflecting surface from any position around the circumference of the apparatus. Rotational motion is imparted to one of the two disks, creating an animated display on the reflecting surface. In another embodiment of the invention, lighting is added above and underneath the disks to illuminate the display and create a vivid and eye-catching attraction under any lighting conditions.
