Some people (idiots) decide right off the bat that fractal art isn't art, even though it, as well as other art, has the ability to effect people's emotions, and it takes a creative mind to make it look good. It's art whether you like it or not. (Besides, if a man pooping in a can and selling it on eBay is art, why not this?)
Fractal art is very trippy looking. It is thought that only hippies love it, and while this may be true for the majority, there are plenty of people who aren't on drugs who also love to look at fractal art.
