Hi Rune,

I have been playing with your particle system and seem
to have problems with the odd particle passing thru the blocking object.

I have tried many variations of the bounce-offset setting (from .01
to .25) beyond that things get hyper bouncy, I still get 1 or 2 particles
passing thru though. 

Mind you the object in question is a clear pipe with a few elbows ( see
p.b.a "more particle tests (2)" ) 

As you know your code better than anyone else, would you have any
suggestions? 

Thanks

I've never been able to do anything about those very few particles that
passes through surfaces despite the pretty solid algorithm. I'm not sure
why exactly it happens. My best suggestion is to make a kill_object
which surrounds the pipe in such a way, that particles that escape the
pipe at wrong places will get inside the kill_object, and thus disappear
immediately.

That's what I thought, I wasn't sure about the kill object.  That will be
a project with this weird pipe of mine, but I'll give it a try.
