Fractals, fragmented or irregular geometric shapes which can be repeatedly subdivided into ever-recurring parts which are each a smaller copy of the shape from which it came, are used in computer modeling of natural structures which do not have simple geometric shapes. Such structures include coastlines, mountains, and clouds.
