For those who don't frequent Danny Gregory's site with the fanatical enthusiasm that I do, this is just too cool not to share. It reminded me of another link I saved some where to share here in which a woman "paints" with sand. I'll return with it in a day or two once I figure out where the heck it is located.
If you haven't seen the movie "Super Size Me" yet, I highly recommend it too. It's a sobering documentary about junk food's affect on the body.
