You could try Chris Huff's particle system patch, AFAIK it also allows to
make pigments from the simulated particles.  

Of course the 'running down' could be problematic, the visibility pattern
I wrote (Megapov MCP) could be used for that, but right now it's probably
not flexible enough.  

Another attempt would be to code something with blobs and maybe use blob
pattern / object pattern.
