Conductive body paint and Arduinos… Nilay @ Engadget writes -

And you thought conductive paint was boring. Say hello to the Humanthesizer, a joint creation between electronic musician Calvin Harris, Sony Music UK, and Bare conductive body ink, which turned 15 bikini-clad ladies into a giant Arduino-powered synth capable of playing Harris’s track “Ready For The Weekend” though Max/MSP and Ableton Live. Each patch is triggered by one of the girls closing a circuit with her hands or feet — you can see the “wires” painted on their arms and legs if you look closely — and the final performance bounces right along in that blurry space between dancing and playing.
