A couple of years ago I attended Lawrence Lessig’s “farewell tour”, before he was to get into California politics. Still a participative representative of the Creative Commons, the subject of the talk was “copy left”, or pushing distribution rights to the public rather than keeping them private. Mash-ups were the example he used, to demonstrate how content in all forms can be used as an instrument, much like a good dj uses turntables to create something new and unique. I really enjoyed this one, by dj Tripp, featuring Lady Gaga and Journey. How else are you going to get them on stage together?
