I’ve once tried to port AVS to GPU: https://github.com/Const-me/vis_avs_dx Already runs ~half of built-in presets.

If I’ll have time for that, maybe I should add custom D3D-specific effects there that weren’t there in the original version. Fluid simulation is one of them. BTW it’s easier to implement with compute shaders. WebGL only support them on Chrome/Chromium and only on desktops, that’s why OP used some trickery with fragment shaders instead.
