This method shows you which points in the complex plane are attractors for the m-set, or at least it shows you where the Z value spends it's time. I've posted the resulting picture to alt.binaries.pictures.fractals as "m-attr.gif". It is colored with the lowest values in red and proceeding through yellow, orange, green, blue and with the highest values as violet. I scaled the values into the color ramp using a simple form of histogram equalization that I developed for coloring mandelbrot images. I find the resulting image fascinating. It is shaped somewhat like the m-set but the features do not really coincide. It consists of many spheroid-like shapes covered with distorted grid lines all wrapped in lace-like wispy features and other strange geometries. I began to wonder what aspects of the m-set cause the various features. It then occurred to me that perhaps some of the features were being generated from points that originally start off in the m-set, and other by points from outside the m-set and that the image was just a composite of the two. I then modified my program to generate those two images. I first created an image of the ordinary m-set which I then used as a reference array which the modified program used to iterate only those pixels that are or are not in the m-set. The picture generated from the pixels in the m-set looks somewhat like the first picture, but a bit simpler (as expected). It looks like a set of various sized spheroid shapes exploding outward from a cloud of red smoke. I posted this one as "bigbang.gif". A totally unexpected thing happened when I generated the other picture (the one from the pixels that are not in the m-set). This one looks very much like some sort of seated Buddha. It looks just like one of those Indian paintings complete with eyes, ears, headdress, arms and crossed legs. It seems to be wearing lots of ornate jewelry and clothing. I'm not kidding. If I were a religious person I would certainly take this as some sort of sign. I posted this one under the name "ganesh.gif" because when I showed it to an Indian coworker of mine, he instantly recognized it as the god "Ganesh" which is the one with the head of an elephant. The nice thing is that you don't need to take my word for it and retrieve my posted image because you should be able to generate the same picture from the above instructions. It's also interesting because it won't really be possible to zoom in much on the features because the picture is the result of the effects of all the points not in the m-set. All three pictures were generated using a max-iteration value of 100,000. They are also very interesting and quite different when using lower values. - Daniel
