Need to randomly make a MC "hover" on the X/Y co-ords

I have great scripts for dynamically growing and shrinking a MovieClip with a fair amount of elasticity, but what I need now is to have several MovieClips "hover" in place on the X/Y axis with random movements, and with the movement easing in and out.

Am I making sense? Does anyone have a script for such movement handy?

Thanks in advance.

code:

---

onClipEvent (load) {

	speed = 1;

	delay = 10;

	moveDistance = 80;

	// Adjust above

	Xpos = _x;

	Ypos = _y;

	timer = 0;

}

onClipEvent (enterFrame) {

	timer = timer+speed;

	if (timer>delay) {

		Xpos = _x+Math.random()*moveDistance*-1+moveDistance/2;

		Ypos = _y+Math.random()*moveDistance*-1+moveDistance/2;

		timer = 0;

	}

	_x += (Xpos-_x)/7;

	_y += (Ypos-_y)/7;

}

I wrote it so you can adjust the maximum distance it moves, the delay, and the speed.

Very cool! It works as advertised - thank you very much.

Do you know how this could be altered so that the "hovering" item moved from a set position, so that if it began in position (20,20) it would move randomly from there, move back to (20,20), and then another random movement and so on?
