"Hands Fixing Hands" is Shane Willis's clever and well-executed transhumanist take on Escher's "Hands Drawing Hands," with lots of crunchy little details to dote upon, including the underlying work-surface, which has the look-and-feel of a real maintenance engineer's well-used case.
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.
