Hi Thomas,

particle system again after a long time. So to answer one of your questions.

#macro particle_gravity  (Clock,Point) <0,-1,0> #end

Should be #macro particle_gravity  (Clock,Point) <0,-9.81,0> #end
In the metric system and #macro particle_gravity  (Clock,Point) 
<0,-32,0> #end in our quaint imperial system. If the clock runs from 0 
to 1 you will only get 1 seconds worth of animation so you will need to 
extend the Final_Clock (+KFn.n) to however long you need.

environment settings yet.
