The large rolling ball sculpture at "Vitensenteret", 
the Science Centre and Exploratorium in Trondheim, Norway.

Here are some pictures of this sculpture which is made by the American artist Fred Crusade.

The sculpture is completely filled with all kinds of mechanisms from simple tracks and loops to spirals, sound producing elements including bells and a citar, lifts and counting devices. The sculpture is hand-operatated through two cranks visible at the front and left side.
