Let me straighten this out. I'm *not* using exact copies of the textures!
I'm not sure where you get the exact copies from that you seem to spot in
the animation... ;)

And no, they're not image_maps but procuderal textures.

I have thought about this myself, but it would be very difficult to
implement as the individual particles don't know if they're on the "inside"
or the "outside".

All I could do would be to apply some random rotation to each particle, but
I'm sure that wouldn't look very good.

Oh so you mean the *code* of your particle system! Why didn't you just say
that. ;)
The term "particle system" covers IMO everything including the concept, the
theories involved, the demo scenes, the code, the documentation, the
resulting images and animations, etc., so I was confused when you talked
about printing out "your particle system".

BTW, I'd never be able to work with code in printed form...

Not a rush, I've just decided not to implement too many new things and
consentrate on getting the first version ready for release instead.

Well, I for one would probably use it if it's flexible enough. Does it allow
me to get access to a particular particle's location at any time? For
example I'd like to know particle X's location at clock=0.6 even though the
clock of the scene is currently only at 0.3. That's not possible with my
system but I imagine it could be possible with yours because of the way it
works.

You see, if that's possible, i could use each particle in your system as an
emitter in my own system and that way get some truely interesting effects.
:D
