Fritz Kahn's 1920/30's illustration "Der Mensch als Industriepalast" depicted the human body as a large, integrated industrial process. This video from Henning M Lederer animates Kahn's vision, really capturing the spirit of the mechanical metaphor for human anatomy.
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.
