Hefting and peering through a high-end camera lens, you get a sense of the craft, the precision engineering, and the thoughtful design that went into it. But look at it in cross-section, as with this photo a neatly bisected Leica Tri-Elmar-M 28-35-50mm lens and the hellish, gorgeous complexity is revealed in a visceral way: "These were actually made by Leica students as a graduation project and boxed as a 'cutaway model' of the lens."

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.
