The famous 'Triple Julia' crop circle at Windham Hill in Great Britain makes a
beautiful digital graphic rendering because of it's fractal composition. In graphics
terminology, 'Fractal' is a term (coined by Benoit Mandelbrot in 1975) referring to
objects built using recursion, where some aspect of the limiting object is infinite and
another is finite, and where at any iteration, some piece of the object is a scaled
down version of the previous iteration.
