"My pythagoras tree page"

I want to be honest at this point:

The following pictures with the associated
explanations are just a means to an end.
It should lead the search engine to this page.

Please do not assume now that it
is a matter of a loveless thing.
I spent a long and concentrated time
with this page.

Why should you develop a page that has been around hundreds of times?
Well: how many times have you photographed a person?

Nevertheless: Read what is written in the box.
You might be interested.

This application is a pure
Pythagoras tree application.
What you generate is always imperative
a fractal, because the structure
is built out of itself.
If you understand this, you certainly are
also interested in:
chaos, math,
Mr. Mandelbrot,
programming,
Mrs. Abby (from "CIS Navy"),
maybe also to biological structures or
generally to the great formula of God.

But what about you?
Normal people don't hang around on such pages. Unless they are forced to.
It could be that you are looking for your challenge. Maybe.

You wanna create your own pythagorean tree program.
You are looking for informations now.

Here are the best tips:

-Terminate all friendships.
  Friends rob you of the time you
  need for programming.

-Create an own code.
  Developing can be less strenuous
  rather than take over and involving.

-Ever: try it with vector geometric solutions.
-Least: use trigonometric functions.

-Consider well in advance
  what the application should be able
  to do and what not.

So; if you should decide to do a project like this
and make it a success - you have my respect!
If you expect someone around you to understand
which odyssey you have taken on yourself,
then you are very lucky.

The Keys:
S-Key: clicks [select_RANDOM].
A-Key: clicks [UPDATE_graphic].
D-Key: clicks [select_RANDOM].
+ clicks [UPDATE_graphic].
T-Key: slides over the screen.
Y-Key: downloads the actual picture.
R- and (+/-) Key: autorun-mode and speed.
Also: up/down-keys to adjust values.

WELCOME to your Pythagoras tree page.
- Short introduction -

On the bottom you see the picture unscaled. It means
the pixels have an assignment 1:1 to your display.
On your left - you see the same picture scaled.
That's for the overview.
To download a picture - make a mouseclick on it.
It doesn't matter to click on the overview picture or the
unscaled picture. You get always the unscaled picture.

Press [Settings].
THERE; be careful with increase
[ITERATION] and [picture_SIDE].
These can push your computer beyond its limits.
[picture_SIDE] is your picture's side length in pixels.

To study your inputed values:
Take a low [Iteration].

|A||S||D||R + -||T| and |Y| to get the picture!
Very useful buttons! Try it!
