It doesn't cancel that "what" at all. First off, this is nothing to do with fractals. Second, these "drawings" are nothing to talk about, as their nature is pretty primitive. That means it sure requires a steady hand (if drawn manually), but the pattern itself is really simple (foremost because they are very much regular). Have you ever head of spirograph? "Drawings" made by it are far more complicated than this one and can be done in a couple of seconds by any kid. Inventing such patterns is really simple and can be done by anyone (me, you, I hope) and doesn't require any talent or even any significant math knowledge.
