Neil Harbisson - the World's first cyborg

This seems more like a stunt. The device has no direct interface to human biology, nor does it seem very practical. The "officially recognized as a cyborg by a government" seems bit fishy too. It sounds like government recognized the device as prosthesis, which isn't that unusual.

http://en.wikipedia.org/wiki/Visual_prosthetic is far more interesting imho, especially when a close friend of mine is losing his eyesight. To be actually able to tap into nervous system opens quite a lot of doors, both capturing data, and sending data.
