That's right... I must have been a bit tired when I wrote the reply...
Attractors are often described together with fractals because they are both
a sort of deterministic chaos.
BTW, did you know that the Lorenz attractor started out as a simple model of
movement in the earths atmosphere?

I can post the source later today (sitting in school right now) but it's not
that much diffrence from your result. A few more spheres (about 40000 more
or so :), smaler jumps and better textures should do it...

Yeah. The page I found this information at had a lot of interesting trivia about
chaos and it's birth. I guess you could call this stuff legends, but they are
based on fact. I notice that most of the best stuff in the scientific world is
found by accident or as a spin-off.

Why would it be a joke? 1% compression means 99% left for quality.

My point is that JPEG isn't a very good format for storing final images...
it takes away the subtle definitions that are provided by lossless formats,
even on 100% quality.
I wouldn't even consider storing my final images in JPEG, especially not
after such long rendering times...

If those are your main concerns, then that reasoning stands to favor PNG over
TGA or JPG. Depending on the system, TGA/JPG's look different and you have no
hope of even guessing how the artist originally intended them. PNG at least
stores the info.
Perhaps at the moment some versions give you bad display because they have
problems. At least these can be corrected.
With other formats, the gamma issue is still around (especially on the PC)
Some programs do gamma correction when displaying, and some do not. So even
with JPG, those problems occur.
Also, one used to be able to say 'Mac gamma' and 'PC gamma' and in each case
be speaking of just one thing. This is no longer true. Just as Mac's had to
come to grip with the fact that all monitors did not have 72 pixels per inch,
so to we need to deal with the gamma issue, and not just try to ignore it.

For the last few years, PNG has been the format, and the W3C has recommended
it. Opera has handled them well for quite a while.
Now, I will say that for this newsgroup often JPG will suit the image fine. In
this case, however, given the large expanses of flat color ( the black
especially ), and the subtle details in the actual image, I would say that PNG
is a good choice for this one. Even on 16-bit display and using 100% quality,
the JPG version looses much of the clarity of the image.

However this causes us to rely on the original author setting the gamma
correct on his system, or having a decent monitor in the first place.

The WC3 recommend everything, there is virtully no file format that they
have not. And as to Opera, how many people use that? from my own site, which
has 20,000 pages shown every month (not sure about unique visitors at this
time) 90% use eith MSIE or Netscape, more tend to use IE at the moment, the
rest is made up of unknowns, webTV, Amiga and Opera reaings in at about 1-2%

As i have said I use a standard raster format for storage, and compress it
myself, Jpegs are only good for the web.

I have no opinion on the subject and don't want to jump into the
middle of this but... I just came across the PNG home page and offer
the link to any and all who so chooses to visit the site. Perhaps
a short browse through the material will offer the added advantage of
a more informed opinion on the subject or it might clear up a few
misinformed or misguided notions on the subject. Perhaps not but I am
a giving person and offer this link freely and expect nothing in return
for having given it. Learn it, teach it, use it wisely, and then shall
you truly live long and prosper.
