Last night at dinner in San Francisco (I'm in town to give a Long Now talk tonight), our waiter noticed that I was wearing a ring made from an ornate spoon handle and produced his home-made money-clip, which he'd fashioned from an antique butter-knife he found at a pawn shop. He said he'd used a hand clamp to hold the handle, wrapped the blade in a cloth dishtowel, and used careful hammer-taps to bend it around. He also said that he flew with it routinely without any problems from the TSA. It was a really nice piece -- he wrapped his bills around his credit-cards and ID to create the necessary thickness.
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.
