3Doodler is a very cool project that is currently looking for investors in Kickstarter: it is the world’s first pen that draws in 3D in real time. “Using ABS plastic (the material used by many 3D printers), 3Doodler draws in the air or on surfaces. It’s compact and easy to use, and requires no software or computers. You just plug it into a power socket and can start drawing anything within minutes”. More details in the video below. Enjoy!
