Some interesting commentary on the whole Grey Tuesday event from a site I discovered thanks to bump.net. (The proprietor throws around a few swear words. If that sort of thing offends you, move along). Plus some more info, this from lessig.org relevant to restoring the public domain. I’m still not sure how I feel about DJ Danger Mouse‘s use of copyrighted materials in his art, but I do think current copyright laws leave artists too little room in the creation of derivative works.
