As said before there are many fractal programs. Speaking for myself,most of the fractals in my images I create with Apophysis.[It Rocks and it's addictive] I also use,fractal explorer,sterlingware and ultrafractal. The first 3 are freeware and the last one you can buy fore a reasonable price. Just type in the name in a good search engine and you will find them. Have fun. Longrider
