I’m crazy about Olafur Eliasson’s Wirbelwerk, an installation of colored glass, metal rods and a light source that throws constantly changing patterns over every surface of the atrium at Munich’s Lenbachhaus. Wirbelwerk, which means vortex or whirlpool, looks like a glittering, light filled cross between a tornado and an icicle. The piece combines three longtime preoccupations of Eliasson’s work: weather, light and space. Not to mention packing in plenty of engineering and optical physics for us nerds. Lots more photos here.
