I didn’t understand this stance when I took the picture. It just seemed an odd way to see the “dark side of the moon” so to speak. When I looked at the picture more carefully, I noticed the black strip of tape, i.e this far and no farther, and that the guy had his toes right at the line, and there was a guard off to the side keeping an eye on him.
What mischief I wonder could you do from the other side that you couldn’t do from behind the line?
It seemed to me that guy had very long arms, and could easily have destroyed the sculpture before anyone could stop him; and who knows, maybe the deconstruction would have lead to something more interesting.
