This 2009 video shows off a curiously effective Hallowe'en prank: the pranksters dressed a child-sized mannequin in a skeleton costume, then posed it, holding a candy-bag, in front of houses, rang the bell and ran off. The homeowners opened their door to find a silent, staring, motionless, costumed "child" -- creepily clever.

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.
