As part of the ongoing serialization of my forthcoming novel MAKERS, Tor.com has commissioned Idiots' Books to produce 81 CC-licensed, interlocking illustrations, one for each installment. Periodically, Tor is adding these to a little Flash-toy that lets you rotate and realign the images like tiles (each has edge-elements that matches up with the others). They've just put up the 5X5 grid, which I'm finding addictively fun.
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.
