It’s a Xmas-time publicity stunt from German engineering conglomerate Siemens AG, which counts a couple of wind power companies amongst its vast holdings. The “Siemens Superstar” was created in collaboration with Munich multimedia artist Michael Pendra and installed on a large wind turbine in Fröttmaning at the gates of Munich, overlooking the A9 autobahn. It was up from November 29 through January 6. The Siemens publicity site has lots more info and some beautiful video. [Thanks, Rachel!]
