Rob Spence, a documentary filmmaker from Canada, has a prosthetic eye that doubles as a video camera.

Spence, who is in his 40s, accidentally shot himself in the eye as a child, and though he retained his damaged eye for years, his cornea eventually degenerated to the point that it needed to be removed in 2007. At that point, he wondered whether he could replace his eye with something that had a little more flair than the typical prosthetic eye.
