Came across this video from the BMW Museum recently and still find it mesmerising.
"The installation consists of 714 metal spheres hanging from thin steel wires attached to individually controlled stepper motors. Covering a six-square-metre area, the spheres enact a seven-minute long mechatronic narrative, creating a representation of the form-finding process in different variations. Moving chaotically at first, the sculpture evolves into several competing forms and eventually resolves as a final shape, which hints at the outlines of well-known BMW automobiles such as the 327, the 1500, the Z4 coupé and the Mille Miglia 2006. The cycle is synchronised with a graphic light strip running around the walls and texts and audio quotes from senior BMW figures on the company’s values and design aims."
