This is Chladni Pattern tile material that is for studying mathematical equations on Shader. I created this pattern because it allows people to make different types of materials without making additional mask textures and you don't have to worry about mask resolution too. You can make floor, wall tile, and decoration with this material.
This is a material function for chladni pattern. You can find the mathematical equation reference is from Rian on https://thelig.ht/chladni/.
