HI, the multifractal world has it´s own laws and as I´m worldwide the only one doing this kind of fractals there is no one to discuss them or to communicate. I just have to get to know them by experience and learn to use them. ; One of them is that´it´s impossible to predict what happens if two formulas have the same center like Newton and Secant. Most of the time one of them is more powerful and the other one remains invisible, but MFR12 has means to enforce this "battle" and then be prepared for something extra special like today. ; This is one of the reasons for me to say MFR12 is fun. I have created it, it´s my world and I can make my own discoveries. Every one is a new "country" ready to explore. ; I just fail to understand why nobody cares to share that experience. Of course it´s complicated to create new images (mostly), but other people have a lot more of those grey cells and should be eager to do this kind of game. Maybe the new input screen can make that decision easier. ; There are two color versions of the same image. It´s a total view and absolutely unique as such. ; https://www.dropbox.com/sh/b8zy8sasia4wgc8/kg7FfOqSKg ; Cheers, Albrecht
