Some lovely unsourced pumpkin-carvery for you, courtesy of a Reddit post that stirred up controversy when someone else posted the same image, claiming to have carved it him (or her) self, and made the front page. Near as I can work out, though, neither of the posters are actually behind the work.
Update: It was carved by Jon Neill.
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.
