His name is Stelios Arcadiou (a.k.a. Stelarc to his fans). This guy waited for years to find a doctor who could implant an ear into his arm. Stelarc says that it is an artistic augmentation of the body’s form. Of course he is not able to hear out of his new ear, but he wants someday to implant a microphone inside it, so other can listen through his arm!
