I have a small collection of rayguns, begun when my wife surprised me on my birthday with one of Weta's stupendous cast-iron steampunk guns. That little shelf of notional, contrafactual armaments in my office is just about my favorite place to rest my gaze. Rayguns kick ass.
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.
