Fractal, by definition, is to repetitively use the same diagram on itself to create a new image. Kind of like a recursion art.

The logic behind this recursion is simple; start off with a very simple shape, say, circle. And with that circle, draw the same circle (of different size) on the original circle. Just keep repeating that process and an fractal image is produced.
It doesn’t have to be standard shapes like circle or squares. All it is needed to be done is to use the exact same image repeatedly, with alteration of size and rotation, to create a fractal art.
