Well put. But while I agree completely, and don't fault Jim for posting this, let's
declare messages about what is on or off topic to be ... OFF topic. Please, no
more messages about the traffic being to high, why you are leaving the list, etc.
As administrator, I will occasionally comment on netiquette issues. In order to
cut the noise myself, I am sending friendly private messages to some of those
who are adding off topic bandwidth in an effort to make the list more useful to
everyone.
Quite a while ago I suggested folks "pay" for off topic messages by including
PARs in their off topic messages. That was one of my all time bad ideas! Much
better is for everyone to take up the challenge of posting only on topic
messages of interest to the folks here.
Thanks!

Perhaps, while a fractal was displayed on the screen, you pressed F6, F7 or F8?
These keys are hotlinked to three display modes that generate b/w images.

I suggest posting *the first few lines* of your new par file, so folks here can
see what it looks like... it's tough to figure this one out just from the error
message you're receiving.

It's been suggested
that time is the fourth dimension
of this universe's fractal.
Problem is, we think of it differently
than we do space.
Einstein was working on this,
as are the quantum physicists.
Could a Fractinteer
figure it out first?

I answered this question before.....you inadvertantly hit one of the f-keys at the
top of your keyboard to produce the black and white. hit f10 and you will go back to
color...or maybe it's f9. happens to me all the time.

Hi Ray,
The key that gives me a B+W image is F6. To return to "my" usual video mode,
[and the color scheme before hitting F6], I hit Shft+F6.

Time has also been sujested as the 3rd dim. for chaos in the population =
(lambda) equation. (For chaos you must have 3 dim.) But I have just =
proved that there is on chaos in the y=3DaL(1-y) eq. And as such time is =
not likely to be the fourth dimension.

We see... what experimental facts lead us to ascribe three dimensions to space. As a
consequence of these facts, it would be more convenient to attribute three dimensions to
it than four or two, but the term 'convenient' is perhaps not strong enough; a being which
had attributed two or four dimensions to space would be handicapped in a world like ours
in the struggle for existence. -- PoincarΘ.

Real computer scientists despise the idea of actual hardware. Hardware has limitations,
software doesnt. It's a real shame that Turing machines are so poor at I/O.

Actually many of the formulae in Fractint already do exactly
this thing when various functions are applied to Z and C. The
par file and formula I have attached below slice a curved
section of the 4-D Julibrot -- a section that is tangent to
the M-set at the longitude of Seahorse Valley -- and project
it onto the flat 2-D plane of the screen.
The shapes of these curved slices can become quite complex, and
being curved in 4-D space are frequently impossible to visualize.

Naw. There are just as many fractals in three dimensions as there are
in two, or four.

The thing to figure out is why we, as human beings, perceive the
dimension of time differently than we perceive the three spatial
dimensions. The Julibrot is an object of four spatial dimensions,
yet we must change one of these dimensions into time if we wish
to see the entire object. When we do this, we see a three-
dimensional object changing in time. But we also see the universe
as a three-dimensional object changing in time. This similarity
leads one to suspect that a great mystery lies just beneath the
vision that we call the physical universe.

It *is* different; although which direction it is in is somewhat a
matter of your coordinate system, the laws of physics do not allow you
to interchange time with one of the spatial dimensions without
noticing.

That's the nature of human experience --- certainly a deep topic.
I'm not convinced I have anything to say on that subject that can
meaningfully be put into words.

I'm sure there is.

Subject: (fractint) color maps
Hi All,
I just started using fractint and am not a computer wiz. Could someone
tell me how to save my color maps so that when I have adjusted a picture in
a deep zoom, I keep that map when I come back out. I want to apply the
same color scheme to other parts of the fractal.
Hope I worded this right.
Thanks,
Amy

Hi Amy,
> Could someone tell me how to save my color maps.
That's very easy. When you have the image on your srceen type <c> and you=
are
in the color-cycling mode. Type <l> and you load a map - you should see
your directory -
type <s> to save the current colors. You will be asked for the name -
beware - if you use a name of a map that exists fractint will overwrite t=
he
old file. Hit <Esc> to leave the color cycling mode.
Cheers and happy fractaling from Germany --Jo--

Subject: (fractint) pars- stars and kaleidoscopes
Last month I was looking at Linda Allison's star
formula (included below) and I found that if you use
the initialization from it ( c=log(sqr(sqr(pixel))*pixel)*0.2:)
that it makes a star or kaleidoscope out of almost anything.
I spent a ridiculous amount of time doing this- here's a few,
and a couple of quat-celtics.
