Abstract:
1. A device for producing a polychromatic effect, comprising: a housing having a top and a bottom defining an interior, said top including an inner and outer surface, and an optical exit port formed therein; a light source disposed within said interior and configured to provide light along an optical pathway normal to said top and through said optical exit port; a first birefringent layer disposed about said optical pathway; a first linear polarizing layer disposed within said interior about said optical pathway between said light source and said first birefringent layer; an object disposed on said outer surface about said optical pathway and configured to receive said light through said optical pathway; a second linear polarizing layer disposed about said optical pathway between said first birefringent layer and an object; a motor disposed within said interior and configured to rotate at least one of said first polarizing layer, said first birefringent layer, and said second linear polarizing layer; and wherein said object has predetermined optical properties being chosen so as to scatter said light at angles not normal with said top.
