This is both completely cool and totally useless: a group of engineers going by Waterloo Labs in Austin, Texas created a way of controlling an original NES by simply moving your eyes.
By using electrodes placed around the eyes to track the movement of a players eyeballs, they were able to jury rig a Nintendo to accept eye movement as controller input. And it works!
Of course, controlling a game with the direction you’re looking makes it pretty tough to look straight at the screen, which is why no one makes it more than halfway through level 1-1 of Super Mario Bros. in this video. But still, impressive work! [Waterloo Labs via Gadget Lab]
