Fractal Domain is one of the best fractal program on the Mac as of 2003. It can plot Mandelbrot and Julia sets, but also arbitrary formula for Rational, Newton, Harley types of fractals. It has a color map editor, and also parameter adjustments such as dwell value and orbit. It comes with a comprehensive documentation that explains the basic math of various fractal types and the program details. Author is Dennis C De Mars.

Xaos is a real-time fractal zoomer.
Fractal curves and L-Systems
L-system is a string-rewriting system that can model recursive processes such as recursive geometric transformation.
