The particles can now flow along any surface.
As always, comments are much appreciated!

i rhink you need many many more smaller particles, moving faster :)

They actually look like they are slithering...I wonder what it would
look like if you hooked several into a chain, and had a "head" at one
end attracted to a specific point.
It looks like you used the ground repulsion method, did you? How did you
implement it? A single ray straight down or forward, a special
combination of directions, or randomly scanning the surroundings?

Yep, and a faster computer!
While testing I'll have to do with this. :(

I think that's because I disabled the bouncing in this test. I originally
made one version that had bouncing too, but there seemed to be a bug causing
the particles to not cycle perfectly when bouncing was used, so I made this
version that use flowing only.

I'm not sure that could be done using this technique. It would have to be
modified anyway.

Nope. It's simpler.

I know, I need many more particles if it is to have any chance of looking
like water...

I had assumed it would take some major changes to your algorithm, or
were you talking about the "sliding" effect itself?

Hmm...a minimum bounce energy? In other words, particles lose energy
until they go below a certain level?

With my sliding method the particles find their own ways. They cannot be
attached to specific points.
> Hmm...a minimum bounce energy?
No *that* simple. That would never give the smooth sliding effect you see.
Not without a huge number of calculation frames anyway.

That's right, but the interesting part is what happens when they go below
that level. :)

It looks like one got away (unless it is a reflection). Sorta pops through
the rock for a moment below the rest of the stream.
