Comic Book on Copyright and Creativity

An anonymous reader writes "Three law professors have written a comic book on copyright and creativity -- focusing on the effects of expanding rights and restrictive licensing on documentary film. The book is available for free online via the creative commons license. High points include Larry Lessig as the Statue of Liberty, a version of the Crypt Keeper who looks like Justice Rehnquist, and comic book riffs from the Silver Surfer. At the end, the book discusses the 'cultural environmentalism' movement which has been getting some attention recently."
