"Caustics" is the term used to describe light that is refracted by a curved surface. In this case, it's specifically the caustics seen on a lightly turbulent swimming pool. This is a simple demo project for a procedural caustics shader. It's tile-able, and very fast compared to other methods for generating caustics (like Voronoi noise). Configuration is simple - just two inputs: scale and speed. The output is a grayscale image that you can do what you like with. The demo shows how to use it as a distortion map and apply some magical colors to it.
