ABSTRACT:
A light display which rotates in response to command signals in the form of sounds, light beams or the like. The display includes a tube having flexible rod-like members coupled thereto and extending outwardly therefrom with the outer ends of the members being provided with essentially point sources of light which, when the tube rotates, trace out generally continuous lines due to the relativey high speed of rotation of the tube. The tube rotates under the influence of an electric motor which receives command signals for causing rotation of the drive shaft thereof. The drive shaft is either connected directly or by gear-down structure to the tube. One embodiment of the invention utilizes the rod-like members which are flexible glass fibers and a light source is disposed to the outer ends thereof. In another embodiment, the members are tubes having light emitters such as light diodes at their outer ends.
