Reed Crawford's Formable Furniture consists of "a couple of interlocking pieces that stiffen at the pull of a wire cable. By manipulating the tension, you can make all kinds of crazy shapes strong enough to act as shelving, seating, or flooring." This looks like fun stuff! Link (via Cribcandy)
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
