I want to make them grow and shrink on their own, each one for himself. Just to make it look organic and living. I know this funktion has to do with a sinus curve, but i dont get it exactly. Anyone can help me out please?? Cheers

(A sinus is a part of your nose). http://processing.org/learning/basics/sine.html You would need to come up with a custom particle class to make particle objects that are easy to give independant behaviour to.
