Matthew Leone from LeoneLabs has just completed his Laser Ball project, it was built inside a tennis ball and uses an Arduino Teensy to power and control 14 red lasers. The ball modes can be changed using a simple mini remote control. The project looks great and apparently took only 5 hours to complete, I am thinking that documenting the project must have taken just as long as the build since the video and pictures of the process look great!
