Hey there... A fractal mathematician might be in a better position to say any thing clear. What my knowledge tells me is that present day fractal science is derived or inspired from nature (and various fractal-like patterns that exist in nature). For example, the buds, shore lines, rock patterns and formations, etc etc Fractal theories have been applied to various purely scientific and social fields as well, (stock exchanges...etc). So the posted image can be stated as a naturally existing fractal itself, or some one may argue that it is not a fractal because it was not created using a specialized fractal software, lol! From its apparent structure, you can call it a line fractal but as said above, only a person who studies and classifies naturally existing fractal patterns can have the definite answer... It may look like just a line but it can be made up of (virtually infinite) number of more complex (and definitely not yet known) fractal patterns.... Take a look at the left end of a standard mandelbrot set. It appears like a line but there is infinite complexity... Thats what I have to say at the moment base on my limite knowlwedge and perception of fractal sciences/patterns... Take care... Salamah Bin Akwa...
