ABSTRACT:
A light display made from a plurality of optical fibers. The fibers are secured to a tube and extend outwardly therefrom, the tube being mounted for reciprocation about an axis extending through the tube and longitudinally of the fibers. In one embodiment, the tube has an arm extending laterally therefrom and a rod coupled to the outer periphery of a rotatable member causes the arm to move back and forth along a curved path to reciprocate the tube and thereby the fibers as the member rotates in one direction. In a second embodiment of the light display, the tube is carried by one of a pair of relatively shiftable members each having a coil thereon so that a voltage applied to the coil of the other member will induce a voltage in the coil of the one member to thereby cause reciprocation of the one member relative to the other member about an axis through the members due to the alternating current "hum" responsive to the inductive coupling between the coils.
