Thanks! And competition results evolution, doesn't it ;-) Actually a 
particle system was my intention immediately when I saw Christoph's 
animations (especially the elastic bouncing boxes) last year probably. I 
HAD to create something similar. I just find it fascinating to be able 
to create a very realistic looking simulations just by applying a few 
easy equations and some carefully chosen logic. It was such a great 
feeling to see the balls bounce the first time!

Oh yes, I didn't pay attention on which Environment to use. The second 
one seems to be the correct one. Well, maybe next time...

It is still very inflexible. I'm now slowly moving things to macros and 
figuring out how to arrange an easy to use, powerful and expandable UI. 
Many things will probably change but the start is promising.

I have only one kind of particles and they are created whenever a 
certain macro is called. It works, but it won't do any miracles :)
