John sez, "Some watch obsessive took this insanely detailed video of the inside of a Panerai movement. It's interesting to see the little balance wheel - the top thing that flicks back and forth - sliding around on the inset rubies." Link (Thanks, John!)
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.
