Abstract

A fused glass light pattern generator in the form of a disc-shaped gobo including fused glass particles of various size and shape. The fused particles have an uneven, multi-level surface sufficient to distort light in response to a light beam being passed through the gobo. The particles may include color producing substances or color may be added to the light beam. The result is an enhanced artistic effect when the images, which are also movable, are projected onto a projection surface which may be a solid surface or theatrical fog.
