HI, ; the reason for the title: since the last update - i told you - it is possible to have the basic shape independant of the first function which now is free to use for the participating frms. ; The result mostly is a new basic image with a huge number of surprising and interesting details, or simple and new structures. ; I´m just beginning to explore the possibilities, so be ready for more. ; One more thing: The frm file contans a second version: Mulktifractal:12cm. CM stands for Compatibility Mode. If an image lately fails to be recalculated possibly it can help. Tell mr and I will inform how to use it. ; https://www.dropbox.com/sh/237cl0fnh3vvsf8/25Vx1Jg2M0 ; Cheers, Albrecht
