And as long as we're on the subject (you didn't think we were even on a subject, did you?), I'm a fan of how Maciej is displaying his oil paintings. For each of his newer paintings (like this one of a West Village scene), he's documenting the progress of the work as it goes along so you can see how the painting becomes a painting.
Update: Eric writes that he uses this technique for displaying how his art progresses as well (sample).
