The Johnny Cash Project.

If you're a Johnny Cash fan or just a creative type with a little time on their hands then you should love this very cool project. It invites users to help build a music video for Cash's last ever studio recording, "Ain't no grave" (sunshine was already taken).

It's not just an exercise in crowd-sourcing of course, it's much bigger than that. It's all about celebrating the man, the myth, the legend and his music or at least his last recording. But the use of user-generated content is incorporated in a wonderfully non-intrusive and selfless way. The creators of the project quite rightly refer to it as a "communal work".

And the real beauty is that this idea could only really work for a handful of artists. The Miley Cyrus project won't be coming to a website any time soon.

Kudos to director Chris Milk, Aaron Koblin and Radical Media amongst others.
