Play superv mario with your eyes

Hi, i was youtubing and found this, i don't know if it's been posted here b4, so anyhoo in short some guys made a nes work with ur eye movements.

Very clever... although the snag seems to be that you need to look away from the screen when playing the game to get Mario to move .

Plus it makes the player look a bit crazy

Still, it's always good fun to see project like this!

I've seen another way of tracking eye movements by using a small camera mounted on a pair of glasses and then using a computer program to track the movement of your pupil. I think using the method that they used in the video would make me dizzy and probably vomit, hopefully not on the nes lol!
