A grocery store in Shenyang, China, has installed a dark-ride-style ride-system that weaves among the shelves. Shoppers climb into the cars and ride through the store, grabbing their groceries as they go. If you miss your shelf, you have to ride through again. Of course, the store also gets to totally engineer your retail experience, taking you past impulse items at eye-level, etc. Link (Thanks, Frank!)
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.
