ABSTRACT:
A multiple pattern display device comprising a plurality of strips interlaced in a weave to expose selected sections thereof. The strips are attached to rollers at the ends thereof, and as the rollers are driven in rotation the exposed sections of the strips within the weave are varied. In this manner various messages can be sequentially displayed. The weaved arrangement of the strips is maintained in a coherent relationship by gearing the rollers such that as the rollers are turned various messages are formed by the exposed group of strip segments. During the transition between messages a kaleidoscopic effect is produced which typically is interesting to viewers.
