Vibration Effect

I am building MASSIVE gongs in my game, and would like to have them look like they are vibrating when they are struck. Are there any tricks or methods of achieving such a visual effect?


The easiest way would to IPO the gongs in two different positions, one position in frame 1 and the other in frame 2. Then whn they get struck, there’s an actuator that says to loop the IPO of 1 to 2.
