| Abstract: |
A rotating display unit comprises a motor drive for rotating the drive shaft, the motor drive being powered by a solar cell which is operative to generate a voltage in the presence of sunlight sufficient to energize the motor drive to rotate the drive shaft, and a light refracting, multi-faceted crystal is mounted on the drive shaft for rotation with the shaft to refract the available sunlight into light patterns which are projected onto a surrounding wall surface.

I claim:
1. A crystal glass display device comprising:
- support means including a drive shaft;
- motor drive means associated with said support means for rotating said drive shaft;
- a light refracting, multi-faceted crystal including means operatively connecting said crystal to said drive shaft for rotating therewith; and
- solar energy means operative to generate a voltage in the presence of sunlight to energize said motor drive for rotation of said drive shaft thereby causing said crystal to rotate and refract the sunlight which causes said solar energy means to generate the voltage into different colored light patterns, said energy means including a panel associated with said support means in contiguous relation to said crystal, speed reduction means between said motor drive means and said drive shaft, said shaft disposed in upstanding relation to said support housing and having an adaptor at its upper end to support said crystal.
