If anyone else really loved that lovely GLSL fluid sim that's been posted here a bunch, I'm working on a beefed up version of that same shader: https://swirltogether.com/
I've added some playful collaborative parts, and I'm doing a playtest of it over the next few weeks before releasing it as a demo on steam at Next Fest.
Fun stuff I added over the years while playing with it:
Multiplayer with settings sharing.
Lots of brush shape/timing settings, mirroring.
Make colliders and import / create masks.
Right click is replay.
Lots of Simulation controls,
Typography tools.
A powerful hotkey system to give a control over everything.
Kaleidoscopic mirroring.
