Abstract
Apparatus for creating optical illusions utilizing a rotating circular disc having alternating transparent and reflective areas according to a predetermined pattern. The reflective area is approximately equal to the transparent area. As the disc rotates at a user's selected speed the user perceives alternating reflected and transmitted images. Thus where the apparatus is positioned between an object and the user the transmitted image of the object is superimposed upon the reflected image of the user and consequently the two images merge to form the desired optical illusion.
