Thanks for joining my fan club! I hope you'll come back and visit again soon.
To answer your question, there really is no secret technique. I use a fractal flame program called Apophysis. It's a freeware program that anyone can use. If you want to try out the basic version, you can download it at www.apophysis.org. There are also updated versions which can be found at http://sourceforge.net/projects/apophysis/files/.
