Fractal Art by Doug Harrington at Fractalarts.com Fractal Definition: A geometric pattern that is repeated (iterated) at ever smaller (or larger) scales to produce (self similar) irregular shapes and surfaces that cannot be represented by classical (Euclidian) geometry. Fractals are used especially in computer modeling of irregular patterns and structures found in nature.
A fractal is a geometric shape that has symmetry of scale. This means that it is a shape that you could zoom in on a part of it an infinite number of times and it would still look the same. This is also called self-similarity. Computer-generated fractals are produced mathematically, and these can create detailed pictures of mountains, plants, waves, and planets. Some mathematicians, such as Benoit Mandelbrot, study nature first, looking for fractal behavior.
