Stick Software has introduced the latest iteration of its Mac OS X screensaver software, Fracture 1.4.

More flexible than the screensavers included within Mac OS X, Fracture generates an infinite variety of fractals based on mathematical formulas such as the Mandelbrot Set. If your Mac has multiple processors, it will use them all to calculate its images as quickly as possible.

Mac users with multiple monitors can set up Fracture to display fractals on all of them, in any of several different multimonitor modes. It allows users to generate and save fractal images that suit your individual taste.

Fracture 1.4 is Leopard compatible and costs $10 (£5.11).
