This clip -- from some sort of Japanese candid camera show -- shows a guy having the bejeezus scared out of him by a woman dressed as a ghost hiding behind a half-silvered mirror.
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.
