I’ve always been fascinated with sacred geometry, and just recently found this video.
Quoting the first paragraph of wikipedia:
Sacred geometry can be described as a belief system attributing a religious or cultural value to many of the fundamental forms of space and time. According to this belief system, the basic patterns of existence are perceived as sacred because in contemplating them one is contemplating the origin of all things. By studying the nature of these forms and their relationship to each other one may gain insight into the scientific, philosophical, psychological, aesthetic and mystical laws of the universe.
