Controlling a 3d printer with a LEAP Motion

Nice video about using the LM to control a 3D Printer. Kids seem to like it. I think I would have loved it as kid 🙂

The setup is using a Leap Motion and a Processing program to generate G-code that is sent to the 3D printer.
Learn how to make it on Instructables.
