Here’s a neat idea from designers razy2. Instead of casting a chair out of foam or silicone, they decided to build one up layer by layer out of what looks like a giant Post-It pad. Because the paper is only attached on one side, you can scribble on the top layer and then just pull it off to clean up, or stick things between the layers. Sounds fun, but I would be pretty scared that I would spill something on it. [via core77]
