Leaves rustling in the wind,
clouds floating across the sky,
waves rolling up and down.
Evolution developed the human mind and eye to notice constant change in nature.
The constant movement- unpredictable in its details and ‘chaotic’ in the most beautiful sense- is apparently good for the soul.
Why else would a fireplace fire or an aquarium have such a relaxing effect? My kinetic sculptures also follow the principle of chaotic movement.
