Replying to pkulak's comment, I think that there have been in the past and probably always will be works of art that do the job they're meant to do in a very short time (even a few minutes or less in some cases - Some of Andy Goldsworthy's projects, for instance), and not just because we have cameras (now) to record these works of art -- A video camera recorded the making of this mural, for instance and so now anyone can see it at any time - It's will last as long as there's a copy of the video or prints from it. In this particular case, it seems to me, the making of the mural was as important as the final result (but of course it wouldn't have reached nearly as many people, if it hadn't been recorded...Still, it was indeed recorded and so it does still communicate something to us). - JV
I never understood people who do work that's so temporary. I suppose you could take a picture, but this guy is spending a lot of time and effort on something that's not going to be around for a very long time.
