Abstract:
1. An apparatus for repetitively lifting and lowering objects to create visual patterns comprising: a plurality of units, each unit having a motor with a shaft, a rotary member with an outer circumferential edge disposed generally perpendicularly to the axis of the shaft affixed to the shaft, and a cord attached at its distal end to a circumferential edge of the rotary member; an attaching mechanism affixed to the proximal end of the cord of each unit; a repetitive element removably connected to each of the attaching mechanisms; a computer or microprocessor associated with the motor and programmed to selectively rotate the rotary members to move the repetitive elements between selected pre-determined positions along a generally vertical path of travel to establish a geometric pattern of repetitive elements; and means for swinging the repetitive elements about their paths of travel.
