Maybe I'm getting sucked in by stereotypes but it seems like the art community is much more concerned with 'selling out' than most.

On the other hand, a plot device from a scifi book (Tad Williams I think?) has stuck me with the idea of creating slowly evolving graphics. If I were an artist I might get pretty excited about a robot who can paint and repaint a mural for me as many times as I want. Being able to change with the seasons or local events might entice me, regardless of how many ads have done the same thing.
