Underwing comprises seven units suspended from an arched frame. Each unit has a ribbed fin-like form with a vessel at each end. A peristaltic pump pushes water from one vessel to the other, causing each unit to pivot from side to side. As a unit reaches its half-way point, it triggers the next, creating an endless loop of motion.
