Abstract

A fiber optic display device reciprocates fiber optics to create decorative optical fiber light displays. The device can include one or more optical fibers contained at one end by a holding member and left suspended freely at the other end. The holding member and optical fibers are functionally attached about a pivot point axis that is across the longitudinal axis of the fibers and the holding member, to a housing. A light source can be affixed to either the holding member or the housing, opposite the freely suspended optical fiber ends, and is oriented to expose and illuminate the optical fibers. A drive means causes the holding member and optical fibers to reciprocate back and forth about the pivot point axis of the holding member.
