My daughter's almost four, and we quite enjoy fishing around on YouTube for great cartoons to watch. I've just introduced her to the Animaniacs (don't tell her, but we've got the whole DVD set coming for her birthday!), starting with the classic I'm Mad, which led me to this kick-ass live-action fan-version posted in 2007.
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.
