Fracture is a screensaver for OS X (now compatible with 10.5 and Intel!) that creates a wide variety of fractal images.

Fracture is able to render the Julia Sets, Mandelbrot Set, Self-Squared Dragons, and Attraction Basin fractals generated using Halley's Method, Newton'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.

It will use multiple processors if you have them, to make its calculations faster, and it will display fractals on multiple monitors if you have them (we have a photo that user Aneel Nazareth sent us of Fracture running on five screens at once, in fact). It can generate a wide variety of color schemes under user control.

And it can even antialias its images, for the maximum in image quality! It can be controlled by the user while it is running, so you can find a color scheme you like, skip images you don't like, hold images you do like, and save images you particularly like to disk.

As you can rely on with Stick Software products, it has a suitably overengineered configuration panel that lets you control many details of its operation.
