Five Dollars: The Paper Currency of 1876 is a fascinating look at the Bureau of Engraving and Printing's decision in 1876 to use paper money as a "showcase for art." The bills are really lush and lovely, like the ceilings of a brothel in a old western movie. Link (via Oblomovka)
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.
