What I'm thinking for a background is something simple. A long hall like these from the Milwaukee art museum. A long hall could represent the life line with the rafting equaling the notches of his life. And having it stark in contrast to the Dan's image shows that nothing in his life is as important as his own appearance. Plus it almost looks like a sci-fi hospital! I think that's why it was used as a setting for the "Lipitor" commercial too. Should be fairly easy to model as well, I can get away with using instances (Thanks Jeff!) for the supports to keep my geo down.
