If you were a kid in the 80s and 90s, you would have spent a lot of time playing the Super Mario Bros games. Flash forward to 2013, now you can play the game too, but this time with your eyes.

Google Glass has pupil tracking sensors, but it only accepts input from voice commands, touch and head movements. Brandyn White decided to take a 3D printed webcam and insert it into Google Glass. He used the camera, the pupil tracking technology to detect eye movement and use said movement as input.

White rigged it up to Super Mario Bros, as a controller and played the game using his eye movements. Imagine being able to play other games with just your eyes.

Check out the video below of White playing the game:
