I love Ned Kahn’s amazing artwork. I just discovered today that three of my favorite pieces of local art were all done by him: the tornado at SFO, the turbulence spheres at SFO, and the uh, wall of dogtags that makes cool patterns down by Moscone Center. Heck, I don’t know what those things are called. But hey, here’s a video of a larger installation, and check out some of the cool videos on Ned Kahn’s website, especially the Duales Systems Pavilion one on this page.
