Thx Krzysztof ! I used Mandelbulber 0.97 too, this one was a combination of Mandelbulb 3d, Mandelbulber 0.97 and Photo Studio. I tend to like Mandelbulber 0.97, it's much more user friendly to punch in numbers. I just started doing fractals 2 weeks ago, so I am still fiddling around which program to use for what
Very intricate with real good perspective and excellent use of colour and shadows.
Just as a sidenote, If I were to do one like this, I'd try using the depth slider to fade away the background. But that's only my opinion without actually trying it; as often as not, an idea like that could turn out better if not applied, and the result is, without a doubt, subjective. I commend this Mandelbulb wholeheartedly!
