Is there a relationship to fractal imagery?  Why are the numbers prime?

Perhaps outside the math nerdery, but why do some people find images
like this so compelling and beautiful?  I guess also interesting would
be why others simply do not.

I feel like Richard Dreyfuss' character in "Close Encounters..."
staring at a pile of mashed potatoes saying, "this is important"
despite having no idea why.
