One could generalize it to inter particle forces, but that would of
course involve quite a lot of calculations. It's interesting how your
'Wild Hose' samples look quite realistic although they don't involve such
calculations.
BTW, the new anim looks good, i tried it in cycle mode although it's
probably not really cyclic in fact. Have you tried it without the
particles disappearing on the ground?

Yes, I think it would be way too slow...

It *is* cyclic.

My system gives each particle a "particle-life". That means that each
particle will "die" a certain amount of time after it is created. I think
that is quite common in particle systems, at least Chris Colefax's Spray inc
uses it too.
Anyway, as a result of the particle-life the particles have to disappear at
some point, but I could increase the particle-life value to make them live a
little longer. I could also shrink the particles during their life-time to
make the disappearing more subtle.

Hah, reminds me of carnivals (not that I've ever been to them, but I've seen
'em on TV).

OK I could have expected to get the same answer you gave concerning your
'glitter' mpg: what I meant is what do _you_ use as an encoder (CMPEG?)
and what do _you_ use to succesfully see the animations??

Why does it remind you of carnivals?

Windows Media Player v6.4, although it does not always loop completely
smoothly.

It can, sort of...it has a half-implemented inter-particle force
calculation that should be useable for it, though it is pretty slow.

I have tried to design my particle system to be as general as
possible...I've used it for spraypaint, fountains, smoke, fire, and
snow...
The closest thing to surface tension would be the inter-particle force
calculation, which is off by default (and isn't finished anyway).
