| Title: |
Illuminating Device Producing a Ripple Effect |
| Abstract: |
The present invention relates to an illuminating device that will create a
continuously moving ripple effect on the area illuminated. The device
comprises a patterned endless belt transported on a pair of driven
rollers. One side of the belt is illuminated preferably by a point light
source. As the belt is driven, the patterns on the two sides pass each
other in opposite directions. This creates a rippled light effect. The
device is particularly well adapted for use with an aquarium to simulate
underwater, the effect caused by ambient light shining through surface
ripple and waves upon the bottom of a body of water.
