This "art sculpture" from Burning Man is currently set-up at here, the corner of San Carlos and Woz Way in San Jose. It is part carousel, part drum machine, and pure insanity.
Around the perimeter of the sculpture and at waist-level, there are a bunch of drum-pads in a huge circle. As people (i.e. you) increasingly beat the drums, it sets the carousel of monkeys into rotation, faster and faster.
There are also these creepy silver monkey masks with these strobe-like goggles you can wear when the monkeys are spinning.
Best of all, it apparently LIGHTS UP at night with full strobe-effect. It will be there for one month, apparently, so saddle up ravers, and check it out.
Fun for the whole family!
