Waterloo Labs has recently come out with the Paintball Picasso. As they sum it up… Paintball Markers + Servos + Webcam + 3D Printing + Laser Cutting + NI myRIO + LabVIEW = AWESOME. The system consists of three robotic paintball guns controlled by servos. They fire more than 10 paintballs a second and can be controlled in a variety of ways to create art. Check out the video.
