Deyrolle's natural-history wallpapers are amazing, even if their site is an unbrowsable, unlinkable mess. These designs would make great additions to any home, presuming you can actually find them and manage to order them.

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.
