Let there be light!
Lightformer was written in Processing and uses the webcam.
** When the game starts you have 20 seconds to shine light into the webcam on your computer such that you create a terrain for your avatar to move around on. Then you try to reach the sparkling square that represents “victory” in the game. And that’s it. Controls are arrow keys + R to restart a level + click to skip the countdown when using the camera.
