First person with an ear implanted in their arm

Stelarc (Australia), a performance artist and academic at Curtin University in Perth, Australia, has had a "third ear" – an ear-shaped implant under the skin of his left forearm – since 2007. The project took a decade to research and fund, but Stelarc eventually found three plastic surgeons who constructed the ear from the artist's own cells and materials used in plastic surgery. The cells then grew around the structure until it was not merely an implant, but a living body part with its own blood supply.

After an unsuccessful attempt to implant a microphone into the ear so that it can really "hear", Stelarc plans to be able to modify the ear to broadcast sounds from his daily life on the internet.
