Although I’m sure there are many, many more fractal-exploring software programs, here are a few that are at the top of the list:
Ultra Fractal 5 (this is the one I use).
Fractal Extreme by Cygnus Software. I tried this one at the same time I was experimenting with Ultra Fractal. For me, Ultra Fractal had many more options and tools.
Xeno Dream. Very professional, powerful program.
Of course, don’t forget to use Google Earth to take a peek at the natural fractals visible from space.

There are many free fractal generators out there on the web. Most of them caused me problems that I was not willing to investigate. My time is too valuable to waste trying to figure what went wrong. For anyone who is very computer literate, some of the freebies might work.
