The Johnny Cash Project is an interactive project directed by Chris Milk and created by Radical Media which allows visitors to create their own interpretation of a Johnny Cash music video. Participants using the websites drawing tool can create their own portrait of Johnny Cash from a still frame reference from the video for "Ain't No Grave" his final studio recording.
Definitely a unique and fitting tribute to the Man in Black.
Sidenote : My introduction to Johnny Cash was via Mark Romanek's powerful music video for the track "Hurt". Still one of my favourites.
