Here's artist Bruce McCall explaining the aesthetic of his retrofuturistic "serious nonsense" illustrations, which nostalgically recall futures that never came to past. It's a very sweet TED talk, and really nails the appeal of old ads, especially old technology ads.
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.
