Spirograph Tutorial

Awhile back I did the Spirograph tutorial. Super simple to follow only about eight steps. Starts off with just an oval, and then I created an Action function. The Action function allows you to create a pattern over and over. Originally I was just going to do a circle that had multiple colors. Throughout that process I decided to create sort of a "black hole". Dropped a picture of space behind it. Kinda has this 3D effect, feels like the Spirograph is coming towards you. Also at the same time it feels like you're looking into the "black hole". Super simple tut. easy to follow, probably will use that later on a different project.
