Strange Attractor
An unusual complex attractor with a high degree of rotational symmetry.

Strange Attractors

Strange Attractors are another type of mathematical pattern. They are closely associated with chaos theory. Strange attractors of all types are constructed by iterating a single (though quite complex) formula, As with C.A.T. fractals pixels are again colored according to how often they are hit. Depending on the exact function used, this process may converge on a few isolated points, zoom off to infinity, converge on a simple curve, or, in the small percentage of cases Spirofractal seeks out, generate an interesting or even beautiful pattern. The type of the formula used is different for each of the three kinds of attractor.
