Move your mouse, the rest is selfexplaining. :D
If not, this is a 2D GPU fluid simulation on a 512x256 pixels texture buffer mixed with another 1024x512 texture feedback loop for the Reaction-Diffusion "Turing Pattern" skin dot synthesis simulation. (A lot of blur levels are precalculated in other textures therefore).
mostly texture manipulation with WebGL glsl fragment shaders
