Scriptographer.org - Spirograph

Generates Spirograph drawings. It simulates a spirograph with two weels, one rolling on the other with the pen being on a variable position on the second weel. When executed, a series of parameters are requested from the user.

Please note:

This script is now included in the Examples/Scripts folder in the Scriptographer package.

spiro-previous.js

So Ive been trying to play with this script in cs3.
But everytime I run it, regardless of the changes I make to it, the output is exactly the same. Doesn't matter what I do I always get the default spirograph.
