This Buckminster Fuller geodesic home model (auctioned off by Wright for $7,500) was a portable model employed by salesmen who went around trying to sell people on the idea of having one built for themselves.
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.
