Cymon (AKA Joe) won the Tinkercad Chess Set Design contest with his design for Action #Chess, whose pieces can be assembled into a Chess Giant. He's documenting the 3D output of his darling on his MakerBot blog.
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.
