The same animation as before, but in larger resolution, spheres replaced
with blob components, and collision detection added.
The collision detection is just a simple bouncing function. The particles
just keep bouncing with the same percentage loss of energy at each bounce.
The good thing is that it should work with not just planes, but any object,
though I haven't tested it yet.

but the particles itself don't have collision-det. between them, have they ?

Thanks Rune.. that is exactly what I had in mind. I trust it wasn't too
difficult?
I'd like to have control over the amount of energy lost on each bounce...
they didn't quite bounce as much as I'd have liked.
Well done (again)! :-)

No, and I have no plans of implementing it.

Not really. I made a weird bug though that took me a while to figure out.

If you mean what I think you mean, then it is already taken care of. You can
set one variable that affects all bounces. You cannot control the energy
loss for the 1st bounce, the 2nd bounce etc.
> they didn't quite bounce as much as I'd have liked.
Well, water drops don't really bounce very much, do they? But anyway, as I
said, you can control it yourself when the system is released.

Thanks you! :)

This looks great in MP7, no cycling in MP6.4 however. I would really
like to see a longer animation with more detail :)

It cycles fine for me with Media Player v6.4...
I'm using Win95.

Maybe later... :)
