One more from the Art Institute of Chicago! You seriously have to check out Simon Heijdens's Shade project. Real-time wind visualization made available indoors in my favourite geometric shape!
"A responsive skin to the windows of a building that filters daylight into a moving projection of shadows that translates the ever-changing natural timeline of the outdoor to the static and perpetual indoor space."
If you get the chance to go to Chicago, Shade is part of the Hyperlinks exhibition, only available until July 20, 2011.....go meow! We highly recommend it!
