Abstract
A passive, reusable visual amusement or warning device includes a handle and a number of light diffracting strips bearing an embossed holographically generated diffraction pattern. The diffraction pattern in the foil is produced in a planar format, and the strips bearing the pattern are displayed and viewed in a curved format. Ambient light striking the strips is diffracted to produce a dynamic, kaleidoscopic readily noticed display of brilliant colors.
