Making Liquid particles: two joining into one?

[DavidOrtiz]

Hi guys, i know i've seen this before, maybe on that flash experimental math site that was all black and white and had a picture of a kid swatting at some molecular looking flies? anyone remember the name of that/

well anyway, what i'm trying to pull off here is like a circle of some sort, all of sudden growing a small little circle and then both of them dividing, or possibly, a two circles(modules, atoms, particles) join to be one.

any ideas?

the only solution I can think of is to have a hit test that removes them and makes a large one with the comined size of the two of them, and then either a "critical mass" or random function that splits large ones into two smaller ones.

i noticed that one of the recent contest entries here, is 'similar' to what i think you're describing.

i have no idea how they're doing that LOL! might be a combination of filters, blend modes and scaling - but it might be a good place to start. i realize it's not quite what you're after but it might give you a foundation to build on.
