Sculpture activated. The conductor in the blue form moves the projector erratically on its track. The projector projects the images of sprinkles in a ring shape. The person conducting the donut attempts to catch the image of the sprinkles on the donut. The conductor of the black door shape constantly spins back and forth causing a small milk carton to move up and down the central ramp. When the milk carton reaches the top of the ramp, it rings a doorbell. All activity freezes for 3 seconds. Sometimes the donut catches the sprinkles, often it does not. The chase continues.
