How to create illustrator full spectrum spirograph

I should point out that this is just one way of how you can create these kind of compositions. I’m sure there are other techniques as well. This shape is inspired by Andy’s creation and recreated for education purposes only. Don’t copy his work, but explore the technique more and create different compositions. For this tutorial I’ve tried to find a simple way, so I can explain things in an easy and understandable manner, inviting you to go further and do some amazing stuff yourself.
