Ray sez, "I was looking for teat cups to build a simple hand vacuum pump milking machine for our new pet goat. And I found this website for milking machine teat cup liners, with the associated disco dancing promotional video.

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.
