Since we don't get much Shadertoy content here, I'll point out that, while this is really cool, there have been some much crazier fluid simulations on Shadertoy.

The most insanely fast fluid sim I've seen there is the one by nimitz: Chimera's Breath https://www.shadertoy.com/view/4tGfDW

And the most insanely weird ones are hands down those by wyatt. They're often conceptual intersections between fluid, particle and wave. It's gotten so weird I have a hard time using words to describe them at this point. For example:

Communication and Grouping - https://www.shadertoy.com/view/wtSSDm

Branching Paths - https://www.shadertoy.com/view/ts33DS

Fluid Mosaic - https://www.shadertoy.com/view/MlVfDR

If you think the first one looks cool, check this out: https://paveldogreat.github.io/WebGL-Fluid-Simulation/

It is even more amazing on mobile with multi-touch, I think you can find it in the app store.

That’s completely and utterly mesmerising. So cool.

Why no multi-touch on non-mobile ? :'(

Well, it uses standard touch* events, so I guess it would work - did you try it?

I did, doesn't work in Firefox on my Surface Pro 3.

While I was playing with it I wondered whether I could somehow make it into a line wallpaper, but then I discovered that there is an app version in the Play Store that has that exact feature.

The wyatt ones look extremely biological to me. Communication and Grouping is slime mold aggregation seen through a phase or differential interference contrast microscope. Branching Paths is some sort of slime mold or fungus colony growth. Fluid Mosaic is epithelial morphogenesis.

That makes me curious: where would I go for more? /r/shadertoy is invite-only, and I'm not sure it's what I want?

EDIT: there's a Twitter feed: https://twitter.com/shadertoy

Some of the examples in this thread load up as empty for me. e.g. the Fluid Mosaic one. Anybody knows why?

Answering my own question: tracking protection breaks some of the examples because some of them try to pull scripts from, e.g. SoundCloud.

I've been on a cosmic horror kick recently and those latter ones feel unsettlingly relevant.

You too?

I've got Prince of Darkness, The Void, Mandy, and the soon to come Color out of Space on my watch list. I'm pretty sure I've seen most of the rest high quality stuff. Annihilation, etc...

It's a poorly designed shader with horrendous performance... almost reminds me of...
