An autonomous musical instrument, "The Bell Tower." An old personal computer, found in the trash, runs a program written in "Q-Basic." The program sends a series of commands out of the parallel printer port, which connects to a circuit that uses the varying signals to trigger different combinations of relay switches. The relay switches, in turn send voltages to the small DC motors at the top of the automaton, which spin small pieces of plastic to 'ring' or 'play' the assortment of bells and springs. Each of these sound-producing elements is fitted with a Piezo-electric contact microphone. All of the audio signals are sent to a hand-built mixer and then to the audio amplifier in the center of the sculpture.
