I'm playing with a particle system. I'd like to be able to specify a rate (in particles emitted/second) for emitters, but I don't want emissions to occur at regular intervals, rather having the number of particles produced in a given second be distributed (albeit fairly tightly) about the specified mean, for a more organic look.

How can I go about doing this?

If you want to generate events as in a Poisson process, you can simply decide how much to wait until the next particle is emitted. The time you need to wait follows an exponential distribution. Does that answer your question?
