This project is created with high power laser pointer, webcam, a Laptop and a video projector. The laser is tracked by the camera, the computer processes the information and then projects the drawing back out through the projector. It can be presented on just about any flat surface. Any passerby can be an artist by just pointing and drawing. Multiple colors can be added as well as different brush tips. Even my grandpa was jumping at the chance to give it a try.
