It unfortunately can't be used to print off 100 paper pterodactyls, but production design student Christophe Guberan has modded an inkjet printer so that the prints fold themselves into unique geometric shapes and patterns as they dry.
Using a very specific mixture of ink and water, the Hydro-Fold prints fold lines on each page. And as the extra moist mixture dries, the paper is slowly contorted and folded along those lines, bringing the page into the third dimension. It's unfortunate that you can't just hit print and have a fleet of paper airplanes automatically delivered, but some of the printer's creations are surprisingly complex. So maybe version 2.0 will have the potential of easily creating an office air force. [Dezeen]
