John sez, "A giant mechanism will park your bike for you in an underground facility in a train station in Tokyo. It packs more than 9,000 bikes tight as sardines, and when you swipe your card to pick it up, it will find your bike and spit it out in 23 seconds!" 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.
