Abstract
Free parallel ends of optical fibers are spaced apart between a viewing window of the one way type disposed to provide an inner reflective surface and a rear facing mirror in back of which the fibers are bundled against which light of constantly changing color is directed. While some free filament ends may be stationary, others are subject to displacement in a manner such that their lit ends appear as pin points of light moving in space.
