Michael Grab has been balancing rocks since 2008, and has since gone viral from what seems to be the gravity-defying nature of his balanced stone sculptures. In fact, Grab’s meditative art works with gravity by slowly arranging the rocks until he finds unseen resting positions. From his site:
a Rigolo Swiss Nouveau Cirque artist Maedir Eugster.
Balance requires a minimum of THREE contact points. Luckily, every rock is covered in a variety of tiny to large indentations that can act as a NATURAL TRIPOD for the rock to stand upright, or in most orientations you can think of with other rocks. By paying close attention to the vibrations of the rocks, you will start to feel even the smallest “clicks” as the notches of the rocks are moving over one another. In the finest “point-balances”, these clicks can be felt on a scale smaller than millimeters, and in rare cases can even go undetected, in which case intuition and experience become quite useful. Some point-balances will give the illusion of weightlessness as the rocks look to be barely touching. But if you look very close, you may be able to see the tiny notches in which the rocks rest.
