When John Hilgenberg got a nutcracker for Christmas, he decided to make it the centerpiece of a huge, delightful rubegoldbergian clock that strikes every four hours, using a combination of eight bells and a complex arrangement to motors and gears.
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.
