I gotta hand it to you, Al - some of those new multifractal images are ACE+ way-cool! The "Underground Mandelbrot" is my favie. I am not able to generate the "Mountain Garden" however - it gets about a third done then the whole rest of it is solid blue. I think this is that "bug" everyone's been talking about. BTW - Xfractint runs in Linux. When you install it on a system which already has windoze, you are given the option of setting up a multiboot configuration. But I'm sure Natalie knew that <g>. JoTz

FOTD 23-05-03 (Isolated Minibrot [8])
by Jim Muth 24 May '03

24 May '03

FOTD -- May 23, 2003 (Rating 8) Fractal visionaries and enthusiasts: Today's fractal is different enough to rate an 8. It has a midget in it, which is the center of attention, but the midget is not at the center of the image. Most surprising, today's 'exceptional' image is merely a step on the way to the real image, which lies invisibly buried in today's scene, and will rate a 9, which equals 'one of the best of all time', when it appears tomorrow. Today's image is named "Isolated Minibrot" for obvious reasons. Most of today's scene consists of 'inside' material made visible by the < bof60 > fill. The areas of radiating bands of color are 'outside' areas that are normally flat, but have been given interest by the < atan > option. When rendered in the normal manner, the scene consists of large areas of black accented by scattered splotches that at one point in the frame appear to vaguely outline a Mandeloid 'atom'. As fractals go in this era of multi-layered and transformed images, today's image might not be considered worth its rating of an exceptional 8. But after trying those options, which are features of another program and draw images that may or may not be considered real fractals, I rejected them, and decided to stick with the more traditional methods of rendering my fractals. When today's image is compared with only my past FOTD images, I feel that it does indeed rate an 8. Whether I have become an old fractal fogy is up to the individual to decide. Today's FOTD image is fast, one of the fastest of all time. It renders in a zippy 38 seconds despite the fact that it consists mostly of trapped points. In today's case, the download will take somewhat longer than the time required to render the image from the parameter file. But as always, the download is available on the internet at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The clouds were plentiful here at Fractal Central on Thursday, but the rain held off, the temperature reached an acceptable 61F 16C, and the dynamically fractal cats managed a pleasant after- noon in the too-tall grass of the yard. When a robin swooped carelessly low, Tippy took a swipe at it, but I fear the duo's bird-catching days are pretty much behind them. Tippy missed the bird by a good meter. I guess the only birds they will eat from now on will be processed turkeys. Rain is in the picture again today, as is a bit of work for me. Hopefully, the fractal duo will resign themselves to a day by the window. Until next time and next FOTD, take care, and be at ease when surrounded by aggressive fractals.

FOTD 24-05-03 (Return to the handle [9])
by Jim Muth 24 May '03

24 May '03

FOTD -- May 24, 2003 (Rating 9) Fractal visionaries and enthusiasts: Fractals rating a 9 are rare creatures indeed, but today, with perhaps a bit of stretching, we have one that I can rate at a 9. I have named it "Return to the Handle" because it is a huge blow-up of a tiny part of yesterday's image, which is located in the narrowest part of the neck of the fan element of the Mayparent fractal. In yesterday's 'isolated' image, notice the tiny dot just beyond the southeast edge of the large scalloped element below the midget. When blown up, this dot proves to be an entire universe, and today's image is a mere speck in that tiny universe. I now must make a confession. To create today's image I made a change in the formula of the Mayparent. I reduced to bailout radius to 30, which changed the original skeletal image into a fully-developed one marginally worth the 9 rating it was given. To have an image that rates a 9 is good, to have an image that rates a 9 and renders in a mere 40 seconds is great. Rarely have we seen such a combined value in the world of fractals. Those choosing to take advantage of the value will render the image from the attached parameter file. Those who choose to download the finished GIF image will do almost as well. The download is available at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Rain fell most all day Friday here at Fractal Central; the fractal cats sulked most of the day. With hopeful hearts, they checked the outdoors several times and from all doors, but regardless of which door they looked out from, the rain was there. They finally satisfied themselves with several treats of tuna, and settled grudgingly into their beds. This morning is once again wet; I suppose the duo will once again be sulky. As for me, it's the beginning of a supposed 3-day holiday, but from the amount of work to be done, one would never guess it. Until next FOTD, take care, and see you soon.

FOTD 22-05-03 (Fractal Claws [8])
by Jim Muth 22 May '03

22 May '03

FOTD -- May 22, 2003 (Rating 8) Fractal visionaries and enthusiasts: Today's image is what yesterday's should have been. Looking at yesterday's image one day later, I see that I over-rated it. It now looks more like a 6 than a 7. But regardless of the true value of yesterday's image, today's image, which mirror's yesterday's, rates a true 8. In fact, if I had more time to color today's image, I might have been able to work it into a 9-rater. As it is, the colors are a bit gaudy, a flaw which costs one rating point. Today's image is located on the northwest edge of the fan, where the fan blends into the surrounding area. Like yesterday's image, today's lies in a vague spiral arrangement in a kind of pseudo-valley. I studied the image for several minutes before I noticed the claw-like features and named it "Fractal Claws". These claws are not to be confused with Santa Claus, whose reality lies somewhere in the range of today's image. In both cases, we can see the picture but not the object. The always-annoying render time of today's image is 15 minutes on my machine, but can be bypassed by letting Paul and Scott do the rendering and going to one of their web sites to view the image. The URL of Paul's site is: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> Scott's site is at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> The all-day rain here at Fractal Central on Wednesday made the fractal cats very unhappy. The temperature of 55F 13C made them even more unhappy. They spent a few minutes under the cover of the porch roof, but soon realized that a pleasant afternoon in the yard was simply not going to happen. They consoled them- selves by sleeping. Today promises more of the same, and in addition, I have more work to do. So until next FOTD, take care, and is today's fractal as real as Santa?

Hmmm. That *is* an odd one. Good luck. I wonder if a pointer is getting trashed. Are any (user-variable) parameters altered? - Bud

FOTD 21-05-03 (Mandelbrot with Aura [7])
by Jim Muth 21 May '03

21 May '03

FOTD -- May 21, 2003 (Rating 7) Fractal visionaries and enthusiasts: Today's curiously festive scene is located right at the top of the 'fan' feature of the May parent fractal. In this area there are many pseudo-valleys with randomly shaped pseudo-buds. These almost-valleys and buds are surrounded and filled not by featureless 'inside' areas, but by higher-iteration areas. Today's image is located in the interior of one of these almost-buds. I have named the image "Mandelbrot with Aura". The blue glow surrounding the central pink area inspired the name. The rating of 7 equals above-average, though I have long since forgotten exactly what an 'average' FOTD fractal should look like. The render time of 7 minutes is also average, and if the internet is running as it should, the download of the completed GIF image will take an average minute or so. The download can be found by visiting Paul's FOTD web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> Perfect weather on Tuesday here at Fractal Central produced perfect cats. The temperature of 74F 23C gave them several happy hours in the yard. When the day was finished, they settled into their beds to sleep peacefully. This morning it is raining. The cats will not be happy. For me, it will be another day filled with work. Until the next FOTD appears in 24 hours, take care, and keep up with the big- time thinkers.
