Fractals are infinitely complex patterns that are self-similar across different scales. They are created by repeating a simple process over and over in an ongoing feedback loop. The common fractal features are infinite intricacy, zoom symmetry, simple to complex, and fractional dimensions.
Example, the fern leaves arrangement provides a great illustration of fractal features. The entire fern is mostly built up from the same basic shape repeated over and over again at ever smaller scales. Fern leaf is neither a one nor two-dimensional shape, but hovers somewhere in between one and two dimension.
