Creepy robotic heads serenade your wallet from deep inside the uncanny valley

No, it's not the Boyz II Men reunion tour, these are three other singing robots manufactured into a performing trio. The animatronic heads from artist Nathaniel Mellor are part of a $75,000 art piece on sale at Art Basel Miami Beach 2009. The artificial faces are controlled by servos which in turn are controlled by a computer. The uncontrolled fear you'll feel when watching the video is, however, completely natural.
