If you have a large enough number of particles, they can appear to flow. 
It works best when the particles are going downhill, though. And you 
have to start them out close to the ground, and keep the bounce height 
from decreasing too much, but if they bounce too high, they won't look 
right.

I know...I once did a particle system with inter-particle forces in 
plain POV-Script...I gave up after a couple multi-hour *parses*. The 
thing was impossible to test, because it took so long to see any results.

I'll look around, maybe I still have that scene file around.

Not yet.

I'll probably implement a kind of force based on object proximity...that 
should allow flowing to work.
