Photographs of natural iterative and fractal patterns. Main Menu
One can with good reason argue that all natural patterns are more or less iterative.
Fractals are one type of iterative patterns and they can be divided into natural fractals and calculated fractals.
Calculated fractals are usually made by mathematical iteration using complex numbers.
The most significant property of calculated fractals is self-similarity in form, regardless of the level of magnification.
Natural fractals share this property, but the self-similarity is usually extended to only one or two levels of magnification. One reason to this is that a natural process is not as 'clean' as a calculated.
