This is "Bio" art or "Wet" art, which is using biology to create art.
The pic is of performance artist Stelios Arcadious, who searched for 10 years before finding a surgeon who would do the surgery. The ear was grown in a lab and then surgically grafted to his arm. He now wants to have a microphone inserted in the ear and a transmitter placed in his actual ear. Guess everybody had different dreams and goals in life; this certainly isn't mine.
