The Evil Genius Simulator: Kinect Controlled Tesla Coils
"The MakerFaire hackerspace ran out of challenges, so they rigged a Kinect up to a pair of Tesla coils. On a whim." — Ben Kidd
Tom Wyatt had a chat with the team from BrightArcs, who'd brought their giant Tesla coils along. A few hours of quick hacking later: it was real.
