A creative agency called Murmure is kitting out its employees with concrete business cards that come with their own miniature shipping palettes. There's a scene in a William Gibson novel (I could swear it was Idoru, but I can't find it) where a Hollywood studio exec passes out business-cards screened on wafer-thin slices of marble, each in its own velveteen slipcase. These (which come with their own little paper boxes) are a nice second, though not nearly so keen as those fictional bad boys.
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.
