Organic shapes and patterns are not always pleasing. Whatever it is in the human brain we want to see patterns, decode them, and store them. Western art has only recently come to be comfortable with the immediate formed and instantaneous. Much of formal art teaching in the past was about traditional skill making, meticulous conformity to what is acceptable beauty.
In the East wabi-sabi was the hallmark of Japanese art. The acceptance of the accidental and imperfect. I would say that abstract expressionism comes close to this basic zen art form. But not entirely. There is spiritual quality in wabi-sabi "impermanence". Life is not perfect so nor should art.
In this way all of nature the beautiful and the ugly are worthy of reflection.
