FOTD 04-12-02 (Cosmic Nursery [3])
by JimMuth＠aol.com 12 Apr '02

12 Apr '02

FOTD -- April 12, 2002 (Rating 3) Fractal visionaries and enthusiasts: Today's fractal shows what happens when a near-linear expression such as Z^1.009+C is iterated. As can be seen from the image, not too much actually does happen, other than a scattering of fragments that barely present a theme. After standing back from the screen, trying to recall what it is that the image reminds me of, I remembered the famous picture of the dust pillars of a stellar nursery which was taken by the space telescope. I quickly decided on the name "Cosmic Nursery". The image could equally represent the last rays of the setting sun striking the snow-capped peaks of a mountain range to the east. In this case, I would have named the image something like "Mysterious Mountains". But names cannot make an image, and today's image has little other than its name going for it. As a result, I could rate the result of today's brief effort no higher than a 3. The wannabe great image can be viewed by running the attached parameter file, which will take 1/2 hour, or by visiting one of the FOTD web sites at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> and: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> and downloading the finished image from there. The fractal weather Thursday was quite pleasant, with warm sun, gentle breezes, and a temperature of 64F 18C. These are cat- pleasing conditions. The cats showed their pleasure by sleeping most of the afternoon. Like all cats, the older they get, the less they romp and the more they sleep. As for me, I'm entering a critical phase of the FOTD CD preparation. As Murphy's law would dictate, the more critical the phase of preparation, the greater the amount of other things to be done. And I'm still keeping the ongoing FOTD's coming on schedule, appearing every day of the month evenly divisible by 3. The next FOTD will appear April 15. Until then, take care, and don't be distracted.

Sorry, but can't track down the web site. But the Fractal Labs screen saver that was (IIRC) recently mentioned on this list, decided to generate an access violation at address 0005d5f83 by trying to read address FFFFFFFF.

I had been given to understand that Jim Muth posts separate versions to the two lists, sometimes with added philosophical musings in the Philofractal one, and that your Web site uses the latter version and Scott's the former. If this is not the case, then there has been a misunderstanding. I see no reason to insult my intelligence here. Also, I don't recall seeing a Cc: header on any FOTDs. Perhaps Hotmail's crummy system doesn't show them to me, or perhaps this is something new. >> Scott's site doesn't include it, and I'm not >> subscribed to the other list. > Why not just subscribe to the other List I already am subscribed to one moderate-traffic list and one high-traffic list. I'd much rather not add another one just to read a particular subset of the postings, especially when that subset is available elsewhere. Also, since when does this list force a poster to edit the reply-to to send replies back to the list? (Yeah I know -- reply-to munging's been the subject of holy wars.

The fractal cats and I
by JimMuth＠aol.com 10 Apr '02

10 Apr '02

There have been rumors circulating recently that the fractal cats do not exist, and that the picture of myself now posted on the FOTD web sites is not really me. These rumors are totally unfounded. The picture is of me, and the cats are very real. Their pictures will be available in the not too distant future, along with a picture of myself as I now appear. But do not expect any great change in my appearance. The cats' appearances are a different story. Jim M. BTW, the cats were not in the building when the photo of myself was taken 5 years ago.

FOTD 09-04-02 (An Oddball Midget [7])
by JimMuth＠aol.com 09 Apr '02

09 Apr '02

FOTD -- April 09, 2002 (Rating 7) Fractal visionaries and enthusiasts: The tiny midget in today's image is truly an oddball, which is why I named it "An Oddball Midget". It's odd because the elements surrounding it have a 6,12 symmetry rather than the usual 4,8,16 symmetry. I don't know why this is so, it seems impossible, but the image proves that it is a fact. Partly because of its artistic worth, partly because of its mathematical curiosity, and possibly because it takes seven minutes to render, I rated the image a 7. That seven minute wait can be considerably reduced by downloading the completed GIF image from Paul's web site at: <http://home.att.net/~Paul.N.Lee/FotD/FotD.html> or from Scott's site at: <http://sdboyd.dyndns.org/~sdboyd/fotd/index.html> But be sure your browser or server doesn't serve up confusion. The fractal weather Monday featured sunny skies and slightly chilly temperatures around 60F 15.5C. The sun, which is now shining strongly on the porch, made conditions there ideal for two intrepid cats, who passed the day watching the world pass by. As for me, I'm still in the midst of the big FOTD CD rush. Progress is being made, but there's still a way to go. Until next FOTD on the 12th, take care, and don't take speculation too seriously.

Well, sometime in the last week the remaining missing image "Fractal Burst" got posted, or whatever. Hopefully this can therefore be the last word on the subject. Strange how it got blown out of all proportion into a federal case! In any event, I won't continue the thread beyond this point. Meanwhile, I'm noticing some duplicate postings appearing -- I got two copies of one posting and four copies of another one recently. What's up?Get more from the Web.

New fractal screen saver
by Thore Berntsen 08 Apr '02

08 Apr '02

This may be a bit off topic, but I hope You will forgive me. You may have seen the Fractint Screen Saver that I wrote a few Years ago. I have now written a new Fractal Screen Saver. I does not use Fractint, but I have found many tips in the Fractint source when developing it. The new screensaver calculates fractals at random and displays them on the screen in different modes. You can find it at: http://home.online.no/~thbernt/fraclab.htm It's freeware! If You have any comments please send them to me. Thore Berntsen Norway thbernt(a)online.no
