I understand why real 3D fluid sim is much harder to do at reasonable speeds than 2D but I wonder if there's a pseudo-3D version that would look good (I'm especially thinking of VR here)

A few transparent layers to add depth? Or something akin to parallax occlusion mapping?

EDIT - this Shadertoy is remarkably awesome despite only running on a 128x128x128 grid: https://www.shadertoy.com/view/wlG3RW
