Fractal generation using GIMP MathMap

MathMap is a GIMP plug-in that allows moderately sophisiticated users to describe image transforms and combinations using a straightforward language. MathMap even builds a user interface for the parameters to your expression, so it is an ideal system for prototyping many types of image processing operations.

Because MathMap operates on a per-pixel basis and compiles expressions with your C compiler, it is fast enough to explore new fractal renderings. Coupled with access to The GIMP's gradients, curves, and other images, MathMap can create images that would be impossible with programs like the venerable Fractint.

I will give a brief introduction to Mandelbrot-style fractals and then throw a whole bunch of assumptions out the door and show you how to make some totally crazy images and animations in MathMap.
