Fantastic read! Not to diminish the original contribution here, but I got curious and started looking for similar projects on the native (in my case iOS / Metal) side that aren't part of the usual suspects like game engines.

These two are kind of fun to play with: https://github.com/andreipitis/FluidDynamicsMetal https://github.com/hagmas/MobileFluidSimulation

Both based on this approach, detailed here by Nvidia: http://developer.download.nvidia.com/books/HTML/gpugems/gpug...

The technique this is based on doesn't create those satisfying tension effects but is more similar to paint flowing on a surface of water, so from a tangibility perspective I'd still love to find something closer to this post's work that runs natively.
