Blue Brown Minimalism
I think this one has a lot of personality.
This has more complexity, it is beyond minimal, but still much less complex than a fractal. It is closely related to the previous images, so I am keeping the sub-header.
Perhaps somewhere there is a measure, and a definition of levels of complexity. Perhaps someday I will look for that. Or perhaps I will stop trying to analyze and classify things that you can clearly see and decide for yourself. It is what it is.
