Here's Nico Roig's interactive panorama, made by stitching together the edges of MC Escher's "Relativity" so that they flow psychedelically into one another in a kind of sphere.
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.
