Hi @netasoreq,

I can’t help but to see Voronoi pattern in your picture.

Do you want your final output to be a static image ? If so, pixel displacement based on [Worley noise](https://en.wikipedia.org/wiki/Worley_noise) (or even [ridged noise](https://www.google.com/search?q=ridged+noise&client=firefox-b-d&source=lnms&tbm=isch&sa=X&ved=0ahUKEwihw-CE2NrgAhVN3RoKHTyvDKsQ_AUIDigB&biw=1472&bih=737)) could be a solution. See [this thread](https://discourse.processing.org/t/2d-displacement-mapping-for-water-effect/3191/4) for more info on noise-based pixel displacement.
