Hey guys

I'm very interested in learning to use Scriptographer however I have very little coding experience, I saw the wonderful images created by the ECAL workshop and was wondering if someone could perhaps explain or maybe give hints about what possible kinds of scripting or processes were being used.

I'm not at all interested in imitating, rather looking to understand and hopefully create my own scripts.

These are the images I'm particularly interested in:
One

Two

Three

Any ideas?
