Today, literally hundreds of artists on LiveJournal have drawn their own version of Batgirl and posted it. The variety is awesome, and some of these (like Tatiana Gill's, pictured here) are really, really good!

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.
