Makeup artist Psycho Sandra created an amazing, gross-out effect for her Hallowe'en costume last year: she created the illusion that she had made a domino mask of her own flayed skin. She's got a whole gallery of bloody makeup effects on her site, including a crazy zombie to die (and come back) for.
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.
