Another great gallery from How To Be A Retronaut (which is fast becoming one of my favorite sites on the net): a gallery of extraordinary vintage exercise machines. The best part of these images are the "athletic wear" enjoyed by their users -- skirts and petticoats, three-piece suits, watch-chains, and shiny leather shoes.
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.
