Animatronic (Head Nod/Head Tilt Animation)Link (Thanks, Waylon!)
These creepy little crawlers was scaring audiences on Halloween (2005) in the CBS movie "Vampire Bats". There were 32 pieces, made up of animatronic heroes, Crawlers, Flappers and static props that were used in the production.
This is a radio radio controlled rod puppet. Animations include a head nod and a head tilt.
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.
