Hal, Jim's Sept. 17th FOTD: FractalOf_Tomorrow: params=45/45/... Jim's Sept. 19th FOTD: RectangleVariation params=91.81/90.94/91.93/89.48/... You say: ---------------------------------- If you remove both of Jim's two degree rotations by changing params=88/88/ to params=90/90/ the rectangle loses its slight curve and becomes very rectangle-like. However, the rectangle's tree-like pattern disappears and zooming cannot locate it. If you increment both of Jim's two degree rotations by by two more degrees by changing params=88/88/ to params=86/86/ the rectangle becomes a comet complete with tail. The rectangle's/comet's tree-like pattern remains in this version. ------------------------------------------ I can't find any reference in either of these images that you refer to with params=88/88/ Am I missing something??
