In 1992, William Gibson released "Agrippa (A Book of the Dead)", a haunting poem about loss and memory that came on a floppy disc that erased itself as you played it. Here's a screen-capture of the Agrippa poem being read out inside a Mac classic emulator. There were other editions, even more esoteric, that you can read about on Wikipedia; as lovely a literary piece as this is, it was an even lovelier artifact.
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.
