ABSTRACT:
An optical ornament, novelty or plaything comprised of a hanging curved prism pivotally suspended for movement in air currents, as a mobile, whereby incident light (preferably sunlight) is transmitted through the prism and projected against a surface (interior walls of a building) to provide colorful, ornamental spectra thereon. The curved prism is triangular in cross-section, elongate, and curved about an axis which lies parallel to the radially innermost face, outside of the transparent member, and extends generally perpendicular thereto. The curved prism is of any transparent material and may be colored or tinted to provide color filtering. The curved prism is provided with a small finger member projecting midway from the radially innermost prism surface. When the prism is supported at or hung from this finger member the prism balances in equilibrium in a generally horizontal attitude. The finger member has multiple suspension points which, when the prism is suspended from different ones of said suspension points, causes the spectrum projection angle of the prism to be varied relative to the horizon.
