This is a simulation of the Gray-Scott reaction-diffusion model running on the GPU. In such systems, an auto-catalytic reaction involving two chemical species is happenning concurrently with diffusion. Despite the apparent simplicity of the model, simulating it with cherry-picked sets of parameters produces a wide range of emerging behaviors.

I’ll make sure to look into it and tell you what the differences are. The patterns definetly look similar to the “wave” or “spirals” preset from my video
