thanks everyone for your comments!
its basically a particle system with two flocks following different behaviours.
the visual style is archieved by rendering each flock of particles using simple radial gradient textures and gl blending. i then apply several shaders like: thresholding, normal calculation, per pixel lighting and displacement mapping – using some photos of real analog liquids i took earlier this year as lenny noticed :)
so its not exactly metaballs as in the book, but looks pretty similar and is way faster than calculating the force fields for each pixel..
I love this video! I am making some similar work now inspired by this and andrew bensons shader work. Id love to check out the any of the shaders your using if your willing to provide(especially curious about the metaball-ish one), or any references you used. Im learning glsl right now. Heres my first test: vimeo.com/3925277
awesome work.
Is that metaballs? What kind of texture is that?

i tried to do something in maya fluids several months ago but this is more like metaballs and sure better than the one i experienced : )
what techniques or type of paint did you use to create the paint images??
