How many do you have? If you have two, you could have one on, and the other on black-out. The one thats on can spin its barrel, move, change color/gobo rapidly, but only for about 2 seconds, then switch to the other light and have it do the same thing, and keep having it switch back and forth. Then, both could come on and have the same color/gobo, and rotate the barrel assembly, not the barrel itself in stop and go movements (to look like sound activation). It could also change color/gobo during this too. Just an idea.
