Humans are accustomed to drawing in the air. We gesture with our hands when talking and will try to illustrate charade secrets by "drawing" objects in space. 3D-printing pens takes those gestures, makes them tangible and, in the hands of an artists, beautiful. Recent 3D-printing pens have been cool, but clunky affairs. LIX Pen, however, is something different. It's light, small and apparently needs no more power than you can draw from your run-of-the-mill laptop. Now it's coming to Kickstarter.
