Simply wonderful movie of Lawrence Lessig's slides and narration from his talk at the O'Reilly Open Source convention. Lessig's been stumping about copyright and the net for a couple of years now, speaking roughly every other week on the subject, and he's done — he says he's going to give his copyright talk once more and then retire it. You can tell he's been working this groove for some time now — this is a very slick and wonderful talk.
(Thanks, Matt!)
