TeamTeamUSA replicated the Josef Hartwig's Model I chess set (created in 1922 at Bauhaus Weimar) as a series of 3D models on Thingiverse, the community for freely reproducable 3D files. Thingiverse user Le Garage refined the models so they could be readily printed, and now anyone can output a set from a 3D printer.
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.
