This GIMP (GNU) tutorial demonstrates how to create a geometric Fractal Design.

Notes
You can quickly Undo a step at any time by pressing Ctrl then Z. Alternatively, click a previous Undo History snapshot - Windows then Dockable Dialogues then click Undo History. In addition, to Zoom in (or Zoom out) of your image; from the top menu choose View then select a Zoom Tool from
the subsequent drop-down list.

Launch GIMP & Organise Its Workspace & Palettes

1/
Create a New Image, and set the following settings, then click OK. (Ctrl then N).







2/
Now, from the top menu, choose Filters then choose Render then choose Nature, and then choose IFS Fractal. Then, setting the following attributes, click OK to the subsequent dialogue box.





Tip
Manipulating the three left-side triangles to the positions below, produces the following leafy effect.





Notes
This fractal-based plugin is truly wonderful! With this versatile instrument, you can create amazingly naturalistic organic shapes, like leaves, flowers, branches, or even whole trees. (“IFS” stands for “Iterated Function System”.)

The key to use this plugin lies in making very small and precise movements in fractal space. The outcome is always hard to predict, and you have to be extremely gentle when you change the pattern. If you make a component triangle too big, or if you move it too far (even ever so slightly), the preview screen will black out, or more commonly, you'll get stuck with a big shapeless particle cloud.

A word of advice: When you have found a pattern you want to work with, make only small changes, and stick to variations of that pattern. It's all too easy to lose a good thing. Contrary to what you might believe, it's really much easier to create a leaf or a tree with IFS Fractal than to make a defined geometrical pattern (where you actually know what you're doing, and end up with the pattern you had in mind).

3/
Congratulations, your geometric fractal design is complete,
and it is ready to save - top menu, then File then Save As. GIMP 2.8 - File then Export.
