The video below depicts a kinetic sculpture created by Fisher Technical Services, Inc., for the Chinese Private Enterprise Pavilion at the 2010 World Expo. The creators
explain, "They reached out to Fisher Technical Services to create their dream of a kinetic sculpture and 120 days later they had a grid array of 1,008 150mm diameter spheres, each suspended and motivated by its own micro winch."
OK, then. You don't have to understand how it works or even why it exists. Just watch.
