Break has a video of "The Only Mario Level That Plays Itself" -- a Mario level where the platforms, monsters, and special blocks impel Mario forward like a ball in a rube goldberg machine, knocking him back and forth and eventually delivering him safe and sound to the end of the level. It's hypnotic and often surprisingly witty viewing. Link (Thanks, Joe)
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.
