Me again!

Well, I've slapped some little code together to show another bit of my
particle-system.

What we see is a blue bezier-spline, which moves along another
bezier-spline (red side ones) and emits particles, that stick to another

(invisible) bezier-spline.
I could have the particles move on, but that was not the purpose of this

demonstration. It's just that I did not see any particle system do an
effect
like that, there's mostly just physical-particle-interaction.

So, instead of moving freely about, particles may also be set to
initially head for
a position, spline or interpolation of vectors (a line, so to speak).

Hmm, interesting. But I'm not sure what actual uses it has. It would
probably look more interesting if you made an example animation of an actual
use of the system.

I don't think it looks very natural. It doesn't look like the particles are
thrown to their location, neither as if they are attracted to it. It looks
like something is artificially moving them there. I think it's due to the
speed and movement, which both seems to be linear.

I'll get at it tomorrow...

Well, the time it takes each particle to move to the designated position is
for each and every one the same, so speed and direction are adjusted
to have them move.
It's just an example of what the system is also capable of, which I haven't seen

much of in other system (as already mentioned...)
