When I do a show, I often use JPEGs or PNGs of optical patterns to create trippy moiré effects on screen. It occurred to me that it would be cool to draw these patterns directly in M8 using the Canvas tool, but it would take forever to draw them by hand. I also know that there are a bunch of graphing equations which create cool repeating patterns, but I'm not a math person, nor am I a great programmer.
Has anyone created a script to draw spiral or epicyclic patterns on the canvas? If I know some scripting, but not a lot of math, are there equations I could put into a script that would do this?
