RiP!: A Remix Manifesto is a 2008 open source documentary film about "the changing concept of copyright" directed by Brett Gaylor. Created over a period of six years, the documentary film features the collaborative remix work of hundreds of people who have contributed to the Open Source Cinema website, helping to create the "world's first open source documentary" as Gaylor put it. The project's working title was Basement Tapes, (referring to the album of the same name) but it was renamed RiP!: A Remix Manifesto prior to theatrical release. Gaylor encourages more people to create their own remixes from this movie, using media available from the Open Source Cinema website, or other websites like YouTube, Flickr, Hulu, or MySpace.
