Mark Frauenfelder's OS X Keynote But why stop with food? I'd like a device that could make anything. If you're as old as I am, you might remember a toy that Mattel made called the ThingMaker. It came with a bunch of metal molds and a little hotplate. You'd squirt the molds full of Plastigoop, which looked like colored Elmer's Glue, then cook it for a while on the hotplate. The PlastiGoop had a great smell, especially when it was cooking. It was probably cancer-causing. Then you'd remove the mold from the hotplate and cool it in a tray of cold water, and peel the rubber parts out of the mold. You could buy all sorts of different kinds of molds? -- little dragons, insects, army men, flowers, shrunken heads, skeletons, disguises. Man, it was a great toy.
