Hi Nekar,
Welcome back to the forums!  :)

like this? :

I'm assuming that it's the big bubble effect of the unstable vortex that you're
trying to do?

Perhaps an isosurface with bubble paths mapped out in randomized sine-wave
spline paths?  That way the bubbles get subtracted from the liquid isosurface,
and whoosh outwards until a max at pi/2 and return to the glyph ring at pi?
Randomizing the path radially would give a fill-in over the whole surface of the
"water".

Of course you could do it with spheres and CSG as well.

We recently partially reworked a bubbles macro, and I did a physically correct
falling raindrop that you could use for bubble shapes as well.

I'd say that you'd want that extended "blooping" of a forcibly extruded air
bubble in water, though.

Maybe model that like the gravitational breakup of a falling stream of water.
