I created a game called Laser Gunner. It's based on the early arcade game Tail Gunner.
Here is a very shotty video demonstration:
Due to the mismatched camera frame rate and laser scan rate it looks very blinky. Also, the brightness of the laser and the focal length of the camera makes it really blurry, so the video really doesn't do it justice. Like, at all. I encourage anyone with a laser projector and an etherdream DAC to check out my github for source code and more information on how the game works:
