The 360Cities people shot a 40 gigapixel panorama of the interior of the gorgeous Strahov library, an 18th century biblioparadise in the Czech Republic. You can spend a lot of time getting lost in this image, which 360Cities claims is the largest indoor image ever shot.
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.
