The musician Calvin Harris used the bodies of 15 bikini-clad lovelies as parts of a large-scaled human synthesizer – a “Humanthesizer,”

How Human Synthesizer Works:

The instrument was created with the use of Bare Conductive, a skin-safe and conductive ink. When the ink is applied to human skin, an electrical current can pass through the body without causing painful electric shock.

Along with the painted ladies and Harris’ painted hands, the synth uses 34 floor pads of the conductive ink. When the performers stand on the pads and touch each other with the painted parts of their bodies a sound is created.

Harris moves along the row of eight “keyboard” girls playing sounds while the “rhythm” section performs a choreographed routine to play the other parts of the song.The technology is truly impressive.
