Hi,  
Im using the fallowing code for a smooth movement for objects, the thing I want is I also want it to be like elastic.

MovieClip.prototype.closefolder = function(newidth, newheight, speed, loader) {  
this.onEnterFrame = function() {  
current\_w = this.\_width;  
current\_h = this.\_height;  
this.\_width -= (current\_w-newidth )/speed;  
this.\_height -= (current\_h-newheight)/speed;  
};

How to do that ?  
thanks
