I've spoken before about Fractals and different freeware programs. I've had great luck with them and have used a program called Apophysis for quite a few years. Unfortunately, due to my lack of skills or frustration levels, I never could seem to do much with them except make interesting patterns.
So I decided to try a combination of both a fractal made by Apophysis 7X and some simple backround filters that work in any Adobe Photoshop program with a Flaming Pear Flood plugin.
Oh I couldn't resist making it a bit complicated you know.
Opened a blank canvas in Elements.
[black and white for backround]
Filter>Distort>Twist [in the opposite direction]
Choose colors for each layer.
Drop in a fractal from Apophysis 7X
Edit colors as you wish.
Flaming Pear is not free, but there are other freeware programs and Adobe Filters that can imitate this.
