After a year of engineering, modeling, and trials, the world’s largest Christmas star now hovers above the A9 Autobahn near Munich’s northern gateway. Affixed to the three blades of the massive wind turbine–70-meters tip to tip–are 9,000 light-emitting diodes (LEDs), all of which use less power than a hairdryer.

The surreal pinwheel is a collaboration between Siemens, a world leader is wind power, and multi-media artist Michael Pendry. 
We’ve seen LEDs used in similar fashion to create patterns and imagery (go Pac-Man!), but this is, well, way big.

The hovering eco-art piece can be seen every day from 4:30 p.m. to midnight and from 4:53 a.m. to 8 a.m.
