My answer to the question would be "both". As fractal art is created with software that uses mathematical parameters and basic geometry to generate the form structure. For those interested in studying the amazing "Fibonacci levels" in their charts for "Crypto Trading", the basic maths is very similar. Some people even say fractals have mystic powers, as fractals can also be found in nature, The bee's honeycomb for example. For me, I just find them beautiful, unique, artistic and a very interesting form of "Digital Art".
