Geekdad points us to a free GPL Windows-Only app called Apophysis for generating Fractals.

I just came across a free, open-source program called Apophysis, which allows even people who don’t really understand how fractals are generated build them easily. It only runs on Windows, unfortunately, but it comes with a lot of examples and seems to be remarkably versatile. The latest release allows the creation of 3D fractals as well, though I haven’t yet tried that feature. The program isn’t aimed at kids, but should be easy enough for most kids who can read on their own or with minimal assistance

The software alone is neat enough, but it’s also popular amongst artists on DeviantArt for the 3D Fractal capabilities.  You can find a great collection of Fractal Images in this list of 40 at WebDesignerDepot.

Shame that it’s Windows only.  It’s written in Delphi (a Visual-Basic type system build on Pascal by Borland), so porting it to other platforms will be difficult.
