Watching these videos made my pulse quicken and my body jerk from side to side as the players executed virtuoso rocket-jumps and precision target-shooting of monsters as they lurched around corners. Link (Thanks, Drew!)
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.
