Abstract
A solar powered rainbow-making device produces a visual display that is created by the interplay of light and a light refractive element that form constantly changing patterns from a rotating crystal. The rotating display device includes a circular-shaped refractive element that is mounted on a base and is turned by a motor driven transmission gear train. The crystal rotates about a horizontal axis as sunlight is transformed into a color spectrum that moves in a circular fashion. The color images can include a plurality of distinct rainbow images that are projected onto the walls and other structures in the immediate environment.
