A major theme of Australian performance artist Stelarc is the concept that the human body is obsolete. As such, his past artwork included hanging himself on a flesh hook suspension, attaching electrodes that control his body and then connecting the control to the Internet so those who logged on can move his muscles at will, and saving his liposuctioned fat for an exhibition.
Now, he's on to modifying the human body, starting with getting a lab-grown ear implanted on his forearm!
