This video is called Fractal Meditation, and was made by William Rood using algorithms in I think 2017, based on when it was published. The creator used 3d Mandelbrot sets to create the fractals, and the only thing I know about the algorithm is that it uses spherical coordinates. I suppose the movement and generation is related to the music that plays, as the colors and what appears seem to be somewhat influenced by the sound. I admire how long the video is, and how unique every single part actually is. Nothing ever actually repeats, even though everything changes so gradually. I think usually when something is this long, parts repeat especially when the sound is so constant, because this video is meant to be meditative. However, because of whatever algorithm is used, everything is so complex and unique that I do not think it would repeat even if the video was an hour long, which I admire alot.
