Heinz Isler’s ice structures.
This is what I would call the art of nature and physics.
Heinz Isler, a swiss engineer, started experimenting with ice just a few years afer graduating from university. He would hang nets, cloth, strings and balloons on trees; supporting them from below with rods. Taking on their natural form through their own weight and the wind, they would then be sprayed with water and ice over to form self supporting structures. A millimeter thick layer of ice was enough to allow the supporting structure to be removed, leaving them suspended.
