I have finally gotten around to looking at the rest of your beautiful fractal art, and I have to say that I love them all. This one is my favorite though I have a friend that makes fractals too, and he says that they are very quick to make, but hard to have them turn out exactly like you want them to. I think that you have figured that last part out All of these remind me imediatly of the elements they are named after. Well done.
Well, I haven't exactly mastered Apophysis - the fractal program. In the case of Elementar, I followed a basic tutorial, which was pretty much useless to me because I already understood how fractals work. Different colors transforming was new to me, and even though I learned how each color changes and how the fractal itself changes when I move reference triangles in the program, it took me quite some time to get it right. Most important part was to figure the right style - the same transformations you make can result in different images if you use different variations. Ugh, enough with the techtalk, it just took a long time to get the style I needed, and when I did, it was pretty easy to create the elementars.
I love tutorials myself. I find that I learn the best if I read about what I am supposed to do instead of just fiddling around randomly. (although random is fun too). Keep up the good work, I can't wait to see what else you come up with. By the way, is Apaphysis a free program? Looking at all your images makes me want to experiment with fractals myself.
Apophysis is completely free, and is even available on DeviantART if I'm right. I myself use Apophysis 2.08 3D hack, because for me that's a stable version. Or, you should find the 'regular' Apophysis 7x, which is also 2.00 or higher, but with a different name.
