Canada's 2D Photography created this amazing Rube Goldberg device out of photography stuff of all descriptions, and made the whole thing so witty and fun that I watched it twice in a row.
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.
