Travelers on Germany’s A9 Autobahn are likely to do some double-takes this holiday. That giant light isn’t an alien–it’s the world’s largest spinning Christmas star.

Power giant Siemens contracted multimedia artist Michael Pendry for the massive project done in partnership with Munich City Utilities. A crew attached 3,000 tiny, colored LEDs on each of three turbine blades using special adhesives. The lights glow in different patterns as the blades rotate, putting on a show evenings and early mornings through January 6, 2010. Since the turbine is part of a local smart grid system, clean energy is powering the lights.

Hat tips to Jacob Gordon at TreeHugger and Bridgette Meinhold at Inhabitat for bringing this star story to light. Maybe next year power companies here in the States will see their turbines as canvases.
