I've long admired happy mutant illustrator Dan Hillier, who produces beautiful line-art collages that combine Victorian woodcuts with original illustration to produce beautiful and surreal effects. He's just uploaded a passel of new work, including the wonderful "Wayfarer," above. You can buy 'em as prints online, or from his stall in the Sunday Upmarket in London's Brick Lane.
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.
