This is great. I remember seeing an earlier version of this same thing a few months back. They've really taken the idea and considered a nice variety of applications. I see people saying smaller pins would make better resolution. Sure. The big problem still is that there are no undercuts to the object because the top surface is extruded downward filling in that space - a much more difficult thing to overcome. I can imagine a version that is not mechanically driven, but either acoustically, or electro-magnetically. If it can do that and still remain interactive - we're in hologram territory people.
