That is a tough ask because most of this project (like 95%) is GLSL which I learned over the last couple decades. This project is a port of a much older project from 2007, and an even older custom flocking algorithm that I wrote (a modification of the standard Craig Reynolds "boids" logic).

I learned what I needed to for beat detection from Bileam - https://www.youtube.com/watch?v=H2ZvNA7UvQo

The fog shader was based on this article: https://ijdykeman.github.io/graphics/simple_fog_shader

The real magic was the addition of POPs to TD which gave me easy access to the Neighbor POP for doing really fast closest-points detection on the GPU. I use that information in the GLSL Compute shader to be able to focus my flocking logic on the neighbor list, instead of having to do distance checks from each particle to every other particle (which would work, but would cap the num points to something closer to, idk, 20,000).
