David and Hilary say, "Prior Art offers made-to-order engravings of patent illustrations in copper, aluminum, and brass. Thanks to the new Google Patents, the USPTO's database is now more accessible than ever. We're inviting customers to search that database for images that speak to them, then we take it from there. After considering a number of user-selected customizations, we engrave the image using our home-built CNC router into metal plate. Add a lovely frame and some matting, and you've got a top-notch conversation piece!"
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.
