I first saw this one at a DIY show in Lille back in december, organized by my father and a bunch of other people. As the title says in an obvious manner, the foldarap can fold, and therefore be transported easily. Here is how it looked after the inventor built it in 8h:
people where around him, listening religiously, not moving for 8h, holding their breath in order not to disturb him. It can create 14cmx14x14 objects, in any color depending on which one you choose. in this picture the resin is transparent, perfect for plastic glasses:
His super-great invention is on an equivalent of kickstarter called ulule, for at least 600$, around 800$+international shipping.
