Very cool ... love performance art, and this is a fresh application of it. Both my Mom and Sis are very good artists, (my Mom well-known in New England for her watercolors, mainly), and when my Sister and I used to take our kids to the ocean, she would make these amazing sculptures coming out of the sand ... dolphins diving, as if the sand were water, and lots of other stuff ... people would gather and take pics, then at the end of the day we would let the kids tear them down, though it always made me sad to let them. She felt like nature was the purest form of art, so wanted to leave it the way we found it. This reminded me of those times, and of how much joy and emotion we can sometimes bring to others ... just by sharing a part of ourselves ... in almost any way.
