Etsy seller WeirdlyCute (an apt name!) makes these "Zombie Stitch" necklaces that make it appear that your head has been sewn on. Alice and I went as Frankenstein and Bride of Frankenstein last year, and this would have made a dandy addition to my Sugru neck-bolts.
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.
