well yes. allready looked up pix_aging. but somehow i wasn`t really happy 
with its results.
what i am looking for is not dust and scratches but filmgrain. the grain 
pix_aging produces
is not really fine structured. but anyway. i think i will try around a 
little more.

well the particle system would be a good thing. but there is the problem 
with openGl. a
3dimensional particle system (well maybe not in commercial 3d applications) 
tend to
be more like little lines then concrete pixels. what i am looking for is 
something like
a 2d particle system which can be textured on geos. i think that could 
bring nice results
in grain generation.

thanks for tips
