Modern art

Last Wednesday another rainy day was promised, so I set out to visit a museum. Unfortunately it wasn't much to my liking, I was outside again within half an hour. One of the few pieces I did like, was the one in the photo. The artist is inspired by the mathematical laws of Pythagoras. The globes sizes are in relation to each other 1 : 2: 3.  The connection in every threesome provides a triangle.
