I have this code. The clip moves in a slow spiral trajectory until it stops. When I increase the number of clips (var totalClips) the behaviour changes. The movement is faster and they make more “laps” until they stop.  
Any hint?  
Thanks.

```auto

MovieClip.prototype.move = function(x, y, radio) {
	this.radio = radio;
	this.onEnterFrame = function() {
		if (this.radio>=0) {
			this.radio -= 2;
			this._x = x+this.radio*Math.cos(t*Math.PI/180);
			this._y = y+this.radio*Math.sin(t*Math.PI/180);
			t += 10;
		}
	};
	delete this.onEnterFrame();
};
totalClips = 1;
for (i=1; i<totalClips+1; i++) {
	attachMovie("circle", "circle"+i, i);
}
for (a=1; a<totalClips+1; a++) {
	eval("circle"+a).move(150, a*50, 150);
}

```
