This is a pattern that I made for studying mathematical equations on Shader. I created this because it can make an unlimited amount of different patterns for wallpaper and carpet tiling. I added a time node to show different pattern at once, but you can make it stop and able to create more patterns than this. The math reference is from Rian on https://thelig.ht/chladni/ .
I have several attempts to make it work because I didn't understand the concept of mathematical equations until I learned this concept from Dokipen from https://www.youtube.com/channel/UC86KxTlE2K1BCF_nwneELUQ here. I am going to try learning this method and hopefully make something useful in the future.
