I followed a tutorial by Kishimisu titled "An introduction to Shader Art Coding" to create this procedural shader art. Pressing most any key on the left and center of the keyboard will change a parameter of the display. All keys are in pairs (Q&W, C&V, G&H, etc.). I had to learn a lot to make this (and more for another one that uses a webcam photo as input). It was a great review of cool math, and how continuous and discrete math can be combined in interesting ways. See the tutorial here: https://www.youtube.com/watch?v=f4s1h2YETNY
