Namely, how do I do it? What I’m trying to do is make a simple SWF with a  
movie clip with a 100% to 0% alpha gradiented white circle with a GradientBevelFilter on it, and I want the angle value to be randomized - I think I could pull off a neat effect with it. Here’s the script I have so far (modified from one of TheCanadian’s tutorials on animating filters)

onClipEvent (enterFrame) {  
import flash.filters.GradientBevelFilter;  
var gb:GradientBevelFilter = new GradientBevelFilter();  
this.filters = [gb];  
this.onRollOver = function() {  
this.onEnterFrame = function() {  
if (gb.angle\<20) {  
gb.angle++;  
} else {  
delete this.onEnterFrame;  
}  
this.filters = [gb];  
};  
};  
this.onRollOut = function() {  
this.onEnterFrame = function() {  
this.filters = [gb];  
if (gb.angle\>3) {  
gb.angle–;  
} else {  
delete this.onEnterFrame;  
}  
};  
};  
}

I’m going to keep messing with it, but if anyone has any suggestions, please chime in! -Dan
