Probably caused by standing waves (as physicists call it). Maybe we can create this or similar patterns by hand by gently sloshing the water in the tub. https://freight.cargo.site/t/original/i/557c73eed3773b2eba7cd7d60caf0f1fe395e0f2f8a322238b62ac1e08f304c8/stonepathmadeira.jpg Stone path in a park in Madeira.

Just like a camera obscura uses a little hole to create an image, the palm leaves leave multiple little holes and correspondingly multiple images of the sun on the wooden jetty.

The reflection makes the characterlessness of the building less poignant. https://freight.cargo.site/t/original/i/4bafcf78664271becb38c00a73fbca76273dddaadc63277375307578ac0b847c/20190722_190334.jpg This pattern of the reflection of the sun can be mapped to the coloured pattern of the bowl. It looks like the surface of the blue paint is recessed a little bit resulting in a focussing of the sunlight on the table. https://freight.cargo.site/t/original/i/873518eee3cb8c2a37e5330535f28b30702958b1cf79368d1a53ea13a724b20a/IMG_3801e.jpg I whished I was the creator of the gray & black pattern on the hull of the ship. https://freight.cargo.site/t/original/i/8b6a0d15ecfffcdbe6023d4b9cad32bd02d1a28dfab89724fab9ece98fd7ff5a/20190814_151040.jpg To reflect, to see things in another light, to be fooled by a reflection, these are the things that will keep our observations sharp. https://olafs.art/Light 2021-10-21T00:08:29+00:00 always 0.5 https://freight.cargo.site/t/original/i/6adf3c489f9d05cb02f672d308faf07a5cf8b4b286feb3c846b01d6123ab3056/Light-kerk.jpg Roof of a church tower in Wales.

Here I use stroboscopic light (tuned to the frequency of the bowl) to highlight the patterns. https://freight.cargo.site/t/original/i/1ccd0d65d3fa5e8445cde5b7b73aa569c1b2a7b0ce863136a879f8767fb90948/IMG_3387e.jpg Notice not only the waves on the surface of the water but also the wave pattern of the coast line: interference of the waves and the sand created this surprisingly regular pattern. https://freight.cargo.site/t/original/i/03b196dabee15b87247140a828d2c525f71c4f0e07f8c59326b9789be0d057b0/Fountain-in-Zwitserland---IMG_3623e.jpg Fountain in Zurich, Switzerland https://olafs.art/Header 2023-09-11T10:56:09+00:00 always 0.5 https://freight.cargo.site/t/original/i/4cc3da5a1a1a753d16c6dc01a85a7be255bd2f49f511fda4720c77e18cbab86d/Portret-Zenith.jpg
