Kinetic Sculpture BMW Museum

Thought this was awesome. It gets really good around 1 min in.

The Kinetic Sculpture is a metaphorical translation of the process of form-finding in art and design. 714 metal spheres, hanging from thin steel wires attached to individually-controlled stepper motors and covering the area of six square meters, animate a seven minute long mechatronic narrative. In the beginning, moving chaotically, then evolving to several competing forms that eventually resolve to the finished object, the Kinetic Sculpture creates an artistic visualisation of the process of form-finding in different variations.
Technology: 714 metal spheres, individually controllable with millimetre
accuracy; cable winches with individual high-precision
motors for each sphere; software for defining animation
paths and controlling motion.
