This is pretty cool looking. It is a pen that lets you draw in 3D. You actually just move the pen around and it extrudes plasticy stuff that cools and hardens when it comes in contact with the air. I can't think of a single practical use for this, yet I want one.
It's a Kickstarter from a company called WobbleWorks. Take a look for yourself.
