In late 2008 filmmaker Rob Spence, caught our attention when he announced his plan to jam a video camera in his skull to replace an eye he lost to an unfortunate accident. Instead of connecting the camera to his brain, Spence sought to become a so-called "lifecaster," recording the feed on an external device. Now his bionic eye is up and running, and he's even partnered with a little company called Square Enix to create a documentary about state-of-the-art prosthetics and cybernetics. The short film, embedded after the break, was commissioned to celebrate the launch of Deus Ex: Human Revolution. But, this isn't just some over-long commercial for a game, it's a serious exploration of cutting-edge leg, arm, and eye replacement technology. Check it out below, but be warned -- there are a few images that might not sit well with weaker stomachs.
