Fractal of the Day
by Jim Muth

|
Fractal visionaries: Today's fractal again comes from my most prolific and unpredictable formula file -- mandnewt.frm. Sometimes these formulas produce blank screens, sometimes they produce blank screens when the inside fill is set to a single color, but rich fractal images when the inside is set to bof60 or bof61, sometimes they produce Newton's images, sometimes they produce mandeloid images, and sometimes they produce a combination of all of the above. Today's fractal falls into the all of the above category. To see how much of it is inside fill, redraw the image with the inside set to 0 and the passes set to t. With the detail removed it will take only a few minutes. To add my part to the survey, let me say that I use Fractint about 80 percent of the time, an old shareware program by Scott Jones called "Recursive Realm" about 15 percent of the time, and all the rest about 5 percent of the time. I haven't yet had time to check most of the other fractals posted here, but things are beginning to slow down now businesswise, so over this weekend I'll see how many of the other posted parameter files I can find time to draw.
