Kottke's posted a great item about a presentation he caught at PopTech on the "world's largest book," called "Bhutan: A Visual Odyssey Across the Last Himalayan Kingdom," which retails for $10,000 at Amazon. Says Kottke, "Turning the pages involved a short walk."

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.
