These are some screenshots of 3 fractal programs I use and one I hope to use. I don't have screenshots from past programs such as Fractint and Tiera-Zon. Click on each image to see it in a larger size.
This is Ultra Fractal, which is the most popular fractal program today. One feature UF has that other programs don't is the ability to layer fractals within the program.
This next one is Apophysis, which generates Iterated Function System fractals, also known as Flames.
This is Incendia, which is the one I have on my screen right now. I discovered it in early 2009, and I'm still on the learning curve. This program manipulates fractals as three-dimensional objects. This shot shows my first Incendia castle formation.
Here is XenoDream, to which I can only aspire. It too is a 3D program, but I haven't mastered it yet. Unlike in the other 3 shots, the fractal shown in this one is not my work (it's an example that came with the program.)
