As part of the ongoing serialization of Makers, my forthcoming book (late October 2009, from Tor USA and HarperCollins UK), Tor.com has commissioned a series of 81 interlocking, Creative Commons-licensed illustrations from Idiots' Books. Each illustration's four edges line up with any of the other illustrations' edges.
Now Tor has released a Flash game that lets you arrange the tiles to form new illustrations, with new tiles being added three times a week, as each new installment comes online. Tile away!
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.
