Inside perspex panels and electro-mechanical system is able to sort over 2000 balls and create images by choosing the relevant positions of either the dark-blue or pale-yellow balls. These images are first created (by anyone) by drawing on a video touch-screen. A microcomputer then controls the functioning of electro-magnetic solenoids in the sculpture that select the order of the blue and yellow balls. The selected balls are inserted from beneath into the sculpture display, causing the old image that was already there to be gradually pushed up and out of the display, and be replaced by the new image. This process takes about 5 minutes. Patterns for timing delays in the movement of respective columns of balls can also be drawn on the video touch-screen. This creates dynamic shape distortions of both the old and the new images during the period of transition from one to the other. Once a new image has been created in the ball display, the scuplture waits fore another drawing to be made and the instruction to show it.
