It could be a stylized exploding galaxy, or it could be a design in a stained-glass window of some grotesque cathedral. It could be these and much more, but it is a fractal. It is today's fractal -- a scene cut in the Rectangular direction through the four-dimensional figure defined by the formula 3.5*((-z)^1.1+z^1.1)+c. The Rectangular direction is my own name for the orientation determined by the imag(z) and imag(c) axes. It is probably the darkest in overall value as well as in mood of all my FOTD's, quite in keeping with the season of Advent which is rapidly coming to a close as the big day approaches. I named the picture "A Fractal Secret" because I'm not sure what it reminds me of, and I didn't want to call it "I Don't Know". The formula behind the image is my RectPMnew -- a formula that I rarely pull out -- not because it is worthless, but rather because I have so many other formulas to investigate and not all that much time to do the investigation. In contrast to some of my recent FOTD's, today's parameter file takes less than 6 seconds to run on a Pentium 200mhz, that is after the minute or two it will take to copy this message to your Fractint parameter directory and run it from there. For those who would rather download the finished JPEG image, that image is available on the Usenet binary newsgroup: The image is also available on the web at Paul Lee's FOTD web site at the following URL: The weather began turning winterish today here at Fractal Central -- cloudy, cold, bleak and raw, with a few periods of sleet and a promise of perhaps a little light snow overnight. The temperature of 38F (3C) was far too chilly for the fractal cats to venture outdoors, so they spent the day alternately chasing each other and stretched out by a radiator. Chilly days are also great for philosophizing, and I had a pretty good day with the philosophy, though I'll hold it until after the holidays, when the world will be in an entirely new era. Until tomorrow, same time same place, take care, and never give up on a fractal unless it gives up on you.

As it is, it can be consulted at www.cribx1.u-bordeaux.fr/fractals/faq/. I was co-editor of the FAQ (for some parts which are in my field my competence), but I have hardly any time to update it and no competence for the mathematical questions. I have no news from Michael for a long time but I think that he retains his copyright. Maybe somebody has ideas to start another new FAQ (with another name). I can help for some parts (programs, galleries, references for web tutorials, mailing lists...). Any suggestion ? ------------------------------------------------------------------------- J.P.

Time warps, of course, are the things fiction writers tell of. They do not exist . . . or do they. A time warp could perhaps best be defined as a discontinuity in the time dimension. But if this definition is accepted, time warps become an every day reality. Last Saturday evening I experienced a time warp. When I finished my FOTD, I ensconced myself in my favorite chair to watch one of those junky old sci-fi thriller movies that they don't make any longer. (For good reason) I inserted the tape into the VCR and saw the movie begin. Then, there was a sudden time warp and the movie was ending. I thought the VCR might have malfunctioned until I checked the clock and saw that the time actually was 75 minutes later than it had been only 5 minutes previously. The time stream had instantly jumped more than one hour into the future. But the time stream had not jumped; I had fallen asleep and for 75 minutes been unaware of the passage of time. I then began thinking of my experience. It could be seen in two different ways. Had I been unconscious for 75 minutes, or had time instantly jumped 75 minutes into the future? From my individual point of view, there was no way of knowing, since both events would have seemed exactly the same to me. Common sense tells me to explain the time discontinuity by claiming that I had fallen asleep and been unaware of time for 75 minutes. But I wonder if this is just another way of saying that my private time-stream experienced a discontinuous leap of 75 minutes into the future. I thought of that event today when I was studying today's picture, which I named "Timewarped Midget". The image is one of a midget sitting back in time, which exists along the Z axis of the image. I'd estimate the midget to be around 30 minutes in the past of the areas around the edge of the image. I have given the scene a dark blue color palette to emphasize the mystery of time. And speaking of time, it becomes relatively unimportant when the parameter file is run. Even the slowest Pentium will finish the image in less than 2 minutes. As always, the JPEG file has been posted to: and to: The fractal weather was rather winterish today. Just a trace of snow fell during the overnight, and that little bit melted by the late morning when the sun broke through. But the tempera- ture of 41F (5C) was too cold for the delicate fractal cats, who passed the afternoon watching the birds at the feeder. Though conditions were good, I exhausted today's philosophical energies thinking about the nature of time. But tomorrow is a new day, and a new opportunity for new philosophy. Until tomorrow at this same time, take care, and time waits for no one.

The viewing conditions here at Fractal Central were perfect, with skies as clear as they ever get around these parts. The moon as I saw it was brilliant, and it did seem a bit larger and brighter than the normal full moon, but the difference was tiny, and I'm not about ready to argue that I witnessed the brightest moon in 133 years. There's nothing loony about today's FOTD. The name I gave it is "Deep Blue Midget", which would have been more appropriate for yesterday's spectacularly blue midget. But today's midget has a blue heart, making it at least somewhat worthy of the name. The little midget is part of the fractal that results from iterating a critical plane of the formula Z^1.5-2*(Z^2.5)+C. The most interesting feature in the picture is the ring of 16 sausage-shaped open areas arranged symmetrically around the midget. Such theme-holes often appear in the Mandelbrot aspect of fractals created when two different powers of Z are combined. I'm not enough of a math expert to know why these holes appear, but when they do appear, it is usually in only certain areas of the fractal. Today's fractal was calculated in 50 minutes while I attended to some last-minute Christmas chores. That time is slow enough to make the a download of the GIF file almost imperative. I posted today's image in GIF format because it suffered too much deterioration when I JPEG'd it. The image has been posted to the Usenet group: and to Paul Lee's web site at: The fractal weather was seasonal today, with variable skies and a temperature of 43F (6C) that kept the fractal cats indoors chasing sunbeams. The weather was also ideal for thinking deep thoughts, though I'm holding my deepest thoughts until next century, when anything could happen. Until tomorrow, take care, and have a happy instead of a hectic holiday season.

The discussion set me to thinking -- what is my favorite fractal? This is a most difficult question indeed. I doubt if any of my FOTD's would qualify, as even the best of them fall from favor within a week of their creation. If the question refers to a particular fractal image, then I have no definite answer, because my favorite image is rarely the same two days in a row. But if the question refers to a particular abstract fractal object, then the four-dimensional Julibrot object created by the formula Z^2+C is my favorite. I never tire of discovering new slices of this single object, which holds within its unfathomable intricacies not only every Julia set, but the Mandelbrot set along with all the perturbed M-sets as well. Though the Julibrot object is my favorite fractal, the MandelbrotMix4 is my favorite formula. (At least until I update it.) This formula almost automatically finds and draws one never-before-seen minibrot after another. Today's image, which results from subtracting a portion of Z^2.5 from Z^2, is a typical example of the formula's efficiency. Being bogged down in holiday activities, I had next to no time to find a fractal worthy of the big day. Then the M-Mix4 formula came to the rescue by creating a fractal that is filled with interesting midgets. The midget I selected is found deep in an elephant-trunk spiral in the East Valley area of the parent image. I named the festive picture "Greetings" both because of the season and because I thought of nothing better. Taking 10 minutes to render from the parameter file, the image may be downloaded in much less time from: and from: The fractal weather was partly cloudy and quite cold today, with an afternoon temperature around 25F (-4C), which kept the fractal cats from even thinking of putting their noses outside. My philosophical muse was as cold as the temperature, so no brilliant new ideas emerged. But it's still 7 days until the next century -- plenty of time to solve some cosmic mysteries. And now I've got to solve the more mundane mystery of wrapping presents and keeping the ever-curious fractal cats out of the wrapping paper. Until next time, take special care, and the best is yet to come.

So I'm writing it now, the morning of the day after it was due. The reason I'm late of course is that there was just too much visiting and other merry-making yesterday, which was December 25. The image itself is one I had on file for just such an emergency. It has been posted to: and to: for almost 24 hours. There's not much to be said about today's picture, so I'll not say much. It was created by the MandelbrotMix4 formula calculating Z^(1.5)+Z(2.5)+C. It's a picture of a standard quadratic baby M-set, surrounded by 'S'-shaped areas of chaos on stalks. The image is actually a bit beyond the limit of resolution, thus the mathtolerance=/0.18 in the parameter file, which will force Fractint to calculate at the correct magnitude. I named the picture "Joyful" because it reminds me of a Christmas decoration. The fractal weather was continued sunny but very cold, with a temperature of 26F (-3C) which kept the Fractal cats well ensconced indoors. Such weather is also perfect for philosophizing, and there's no time of the year better suited for philosophy than the Christmas season, when everyone gets all nostalgic about things that they can't even define. Despite the rush, I found time for much deep philosophical thinking. I'll share my thoughts starting January 3, 2000. Until next time, which will be in only 12 hours, take care, and thank goodness Christmas comes only once a year.
