A beautiful fractal screensaver.
Fracture is a shareware screensaver for OS X that creates a wide variety of fractal images. It can render the Mandelbrot Set, Julia Sets, Self-Squared Dragons, and Attraction Basin fractals generated using Newton’s Method, Halley’s Method, and two other root-finding algorithms. It can make images using advanced fractal imaging techniques like orbit traps, periodicity analysis, and binary decomposition, and it can use several different parameterizations for even greater image variety.
