Lots of fluffy, boiling clouds of low altitude, under the action of strong currents break and stir, without stopping. The sun rays are projected onto them, thus creating a lot of combinations of white, blue and gray. From place to place, temporary are created windows to the high-altitude clouds, which are also partially covering the sky. Everything is constantly moving, against a blue sky background.
