This collection of German postcards were originally give-aways in Hildebrands chocolates in 1900 -- they depict the world as it would be in 2000. Included are a water-unicycle, slidewalks, locomotives pulling houses, personal airplanes, weather control systems, amphibious railways, police X-rays for seeing through walls, and, of course, zeppelins. Beautiful artwork, too. Link
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.
