Every year cameras become more and more affordable, putting models that were exclusive just a few years ago easily within our reach. However, here's one camera you'll probably never get your hands on:
[Canadian Rob Spence's] eye was damaged in a childhood shooting accident and was removed three years ago. Now, he is in the final stages of developing a camera to turn the handicap into an advantage.
Mr. Spence said he had an epiphany after watching the 1970s television series 'The Six Million Dollar Man'' and then looking at his cell phone camera and realising it could fit into his empty eye socket.
With the camera tucked inside a prosthetic eye, he hopes to be able to record the same things he sees with his working eye, his muscles moving the camera eye just like his real one.
Spence said he plans to become a "human surveillance machine" to explore privacy issues and whether people are "sleepwalking into an Orwellian society".
