I am playing with the code on the Kirupa site for random motion:  
[http://www.kirupa.com/developer/actionscript/random.htm](http://www.kirupa.com/developer/actionscript/random.htm)

Is there a way to make it so the balls only fall down and not come back up again? I want to make an effect like rain. Any ideas?
