Here's a three-part video-lecture by Bruce Sterling on the subject of "generative art" -- art that is created by a process that is in turn created by an artist. These are the artistic progeny of the spirograph and the kaleidoscope, and Bruce has an acerbic, thoughtful and skeptical approach to the subject.
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.
