Pendulum Clock

At first glance, the giant erector-set-like structure seems to be a realization of one of Leonardo Da Vinci's mechanical inventions. Totally open and exposed, it constructed of steel, ropes, bicycle chains, and a bowling ball. The whole structure stands twenty-four feet tall. The clock has large teeth which mark off the minutes of an hour, as well as hour and minute hands.
