A nursing student named Janelle asked Adventure Time character designer Matt Forsythe to interpret the "Wong-Baker Facial Grimace Scale" -- used to help kids describe how much pain they feel -- using Finn. The result is just great.
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.
