Seen at New York Comic-Con, which I'm presently attending: illustrator Pat Dorian's excellent t-shirts, which took top honors in my personal "t-shirt I would buy if I didn't have about 40 times more t-shirts than I could possibly use" competition.

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.
