Chris sez, "This is a video of me doing one-handed origami, making a flapping bird in each hand at the same time, one with my left hand and one with my right. I put just a single one-handed video up on YouTube last year and there was like a stream of folk complaining it was fake, so I figured out how to debunk it". Link (Thanks, Chris!)
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.
