Scratchless Discs are blank CDs with small raised bumps around their perimiters that keep the disc's data from coming into contact with your desk when you set it down, reducing the likelihood of scratches that render discs unreadable. The discs have some other clever features, like a bevelled edge to make it easier to lift them off of flat surfaces.

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.
