controling particles

Hi, Im completely new in quartz composer and as my first project Im trying to make kinect controlled patch using particle tools, but my problem is that I have to force particles to stay on place (with bit buzzing move) and make smithing like dusty circle. (someone will move them by moving hands and making oscilater noise through max/msp) The problem is to force particles make some shape (emitter does not work). Tried to use particle cloud from 1024 but I can't make it work. Any help?
