SPIRALS - fractal styles

This is going to be a new series of news articles for teaching and widening the audience of fractal art.
I would like to introduce everybody to different styles and genres, we have in fractal arts, whatever the program you may
use for making them.
Lets start things of a bit easy with one of the most common and popular shapes - Spiral. What is a spiral ? In mathematics
it's a curve unfolding from a central point, creating proportional bigger curve the farther it gets from the point.
We have many types of spirals in math as described by their functions. The most used in fractal art (not the only one) is a
logarithmic spiral, which is characterized by equiangular spiral growth, described first by Descartes and also known later
on as "the marvelous spiral". It's roots are in nature plants, fern leaves, shells, atmospheric changes and even cosmic
systems forming spiral nebulas (see Logarithmic_spiral >> [link] ).
If you interested in the full mathematical meanings and formulas you can look up the basci definitions and spiral types in
the wiki >> [link]
Since all our knowledge comes from nature I wanted to show you some examples of that, nature and then man made
things mimicking it.
