Absolutely The Coolest Chair Ever
This is so cool. It's a folding chair that can be several different chairs or even a couch (the link goes to a demonstration video). Really an outstanding design. It is one of those counterintuitive things that I suppose can easily be explained by physics and weight distribution and all of those kinds of things I don't understand. The chair is made of paper and reminds me of those sculptures made out of the folded pages of books.
One of these days I will get an old book out of one of the boxes in the garage and try to do one of the sculptures.
