Out of the endless, literally infinite, possibilities of change in the development of a fractal image, the moment you select a specific change over any other you have moved from the observer to the creator. The same choices apply at every point in the development. So that by the 'butterfly effect' from chaos theory your image is truely unique after only a few iterations. Unfortunately it often looks a lot like countless other flames or spirals or swirls, etc. Therefore to come up with something that not only is unique but also looks unique the artist is driven to go further, to create a unique composition or feel, or sometimes even meaning. This is true for any art form. There be the magic. Tim
