The Horniman museum in London has this German wood-turned disc from which individual toy cows may be sliced in its Handling Collection. For some reason, I never imagined that this is where wooden animals came from, but it's an awfully clever way to make them.
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.
