Bonjour,

Paths can be saved in SVG format.
The script-fu is in the archive "Spirograph_for_beginners_Version2.zip".

File > Create > Patterns > Spirograph for beginners ...

This script is an adaptation of "Epicycloid_for_beginners.scm" ( viewtopic.php?f=12&t=7276#p92776 ).

****
Edit 20130520
Version 2
This script is modified to create a small path "Path_Inbetweener" to use "path inbetweener" created by Ofnuts.

That would make a fine plate to eat off of Samj.

Thanks samj! I don't know quite what I'm doing with it, but it's sure fun.

ooooh, for beginner, I will grab this one. I like script fu only because I know where to put it. Everytime I try to put in a py, it never shows up for me.

Super cool effect with Levels and then curves.

It is possible to create Epicycloids and Hypocycloids with this script-fu.

Use a very small coefficient value for the frequency. Example KF = 3.5

To create an Epicycloid :
Frequency 1 = 10
Frequency 2 = Frequency 1 * KF = 10 * 3.5 = 35
Radius 2 = 50
Radius 1 = KF * Radius 2 = 3.5*50 = 175

To create a Hypocycloid :
Frequency 1 = 10
Frequency 2 = Frequency 1 * KF * -1 = 10 * 3.5 * -1 = -35
Radius 2 = 50
Radius 1 = KF * Radius 2 = 3.5*50 = 175

This script is now very, very slow. Enough time to quietly drinking coffee :rofl
