TP on Joost
Twin Peaks has just been released on Joost. You can watch the entire series (minus the pilot) on this service. The video is pretty good -- just make sure you have a fast connection if you plan on watching it in full-screen. All you have to do to get started is download an 11MB file and install it, and you're good to go.

Perfect for when you're sitting at work and want to do something other than work!
