## Introduction[edit]

Here you can find algorithms and examples of source code for drawing fractals.

Multiplatform, open source and free tools are suggested.

Make a good description of programs/algorithms. A program is as good as it's documentation.

Try to disjoin computing parameters from creating images ( in other words : "separate the calculation phase from the colouring phase" Claude Heiland-Allen) It can slow the program but makes it easier to understand the algorithm ).

If it is possible make one-file programs.
