Awesome Free Fractal Program

I found this awesome program called Apophysis 7x that you can download at that link. It is a semi-easy program to make fractal art with. I've had to find a lot of tutorials online so I could have a bit of idea of what I'm doing. Sometimes I can make some nice things, sometimes I have to tell myself that that particular image isn't working out and I'm not making it any better.

I made these 4 pictures with the Apophysis. Then I took it to Pixlr (a free image editing site similar to photoshop, but browser based) to make it darker in some places and highlight it in others to give a nice glow look.
