A motor is secured in the interior of an enclosed housing. The motor shaft extends outside of the housing. A turntable is connected to the motor shaft on the outside of the housing. The turntable is located in a recess in the housing. An illusionary disk is held on the turntable. A potentiometer controls the speed of the motor and thus the speed of the turntable to produce different optical illusions from the illusionary disk. A light is located in the housing near the turntable. The light flashes through openings in the illusionary disk to produce additional optical illusions as the illusionary disk rotates.
