I love this video clip of a kinetic sculpture at the BMW Museum in Munich. I could watch it for hours.
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.
I wonder how much a trip to Germany would cost?
