Moving Chains is a monumental 110-foot long kinetic sculpture that evokes the hull of a ship, built from steel and Sapele, a tree native to West Africa commonly referred to as African Mahogany. Inside of the sculpture, nine chains run overhead: rotating on a maritime sprocket system, eight of the chains represent the pace of the currents in New York Harbor, while a ninth central chain moves more quickly, mimicking the pace of a ship in transit.
