Shadertoy demos

Shader experiments

Links to some of my demos and code in shadertoy. Shadertoy is a platform for creating and sharing shaders. "Shader" is a type of program that runs on the GPU and can create complex visual effects in real time. The shaders linked here are mostly visual experiments related to physics concepts, but they can also be appreciated for their artistic and technical qualities.
