[COLOR=#0066cc]Mac OS X Dock menu (without lmctween)[/COLOR]
[COLOR=#0066cc][/COLOR]
[COLOR=#0066cc]Here is the code:[/COLOR]

align = bottom;
centerx = Stage.width/2;
centery = Stage.height/2;
menuholder = createEmptyMovieClip("menuholder", -1);
menuholder._y = centery;
menucount = 10;
menuitems = [];
miwidth = 20;
miborder = 1;
startx = centerx-((menucount-1)*(miwidth+miborder))/2;
trace(startx);
for (var i = 0; i<menucount; i++) {
 var menuitem = menuholder.attachMovie("menuitem", "menu"+i, i);
 menuitem._x = startx+i*(miwidth+miborder);
 menuitem.id = i;
 menuitem.onRollOver = function() {
  _root.selected = this;
 };
 menuitems.push(menuitem);
}
onEnterFrame = function () {
 var width = 0;
 for (var i = 0; i<menucount; i++) {
  var xxm = menuitems*._xmouse;
  var yym = menuitems*._ymouse;
  var xm = Math.sqrt(xxm*xxm+yym*yym);
  if (xm<50) {
   menuitems*._xscale = menuitems*._yscale += ((200-xm)-menuitems*._yscale)/3;
  } else {
   menuitems*._xscale = menuitems*._yscale += (100-menuitems*._yscale)/3;
  }
  width += menuitems*._width;
 }
 width += (menucount-1)*miborder;
 var xpos = Math.round(centerx-width/2);
 for (var i = 0; i<menucount; i++) {
  xpos += menuitems[i-1]._width/2+miborder+menuitems*._width/2;
  menuitems*._x = xpos;
 }
};

Here is my as3 code:

package com.boru.display 
{
 import flash.display.MovieClip;
 import flash.events.Event;
 import flash.ui.Mouse;
 
 public class DockMenu extends MovieClip
 {
  private var centerX: uint ;
  private var centerY: uint ;
  private var menucount: uint = 15;
  private var menuitems : Array ;
  private var startx: uint;
  private var menuwidth: uint = 40;
  private var space: uint = 2;
  private var container: MovieClip;
  public function DockMenu() 
  {
   init();
  }
  
  private function init () :void 
  {
   centerX = this.width / 2;
   centerY = this.height / 2;
   menuitems = [];
   startx = centerX -((menucount - 1) * (menuwidth + space)) * 0.5;
   for (var i : uint = 0 ; i < menucount; i++ ) 
   {
    container = new AlbumContainer ();
    container.y = centerY;
    container.x = startx + i * (space + menuwidth);
    menuitems.push(container);
    addChild(container);
   }
   this.addEventListener(Event.ENTER_FRAME, dockEnterFrame );
  }
  
  private function dockEnterFrame (e:Event) : void 
  {
   var mwidth:Number = 0;
   for  ( var i:uint = 0; i < menucount; i++)
   {
    var xxm:uint  = menuitems*.stage.mouseX;
    var yym:uint  = (menuitems*.stage.mouseY) - 300;
    var xm:uint   = Math.round((Math.sqrt(xxm * xxm + yym * yym)))/ 100;
    
    if (xm < 50 ) 
    {
     menuitems*.scaleX = menuitems*.scaleY += ((2 - (xm/100)) - menuitems*.scaleY) / 3;
     trace("if " + menuitems*.scaleX);
    }else {
     trace("else " + menuitems*.scaleX);
     menuitems*.scaleX = menuitems*.scaleY += (1 - menuitems*.scaleY) / 3;
    }
    mwidth += menuitems*.width;
   }
   /*
   mwidth += (menucount -1 ) * space;
   var xpos:Number = Math.round(centerX - mwidth / 2);
   for ( var j : uint = 0; j < menucount; j ++ ) 
   {
    xpos += menuitems[j - 1].width/2 + space + menuitems[j].width /2;
    menuitems[j].x = xpos;
   }
   */
   
   
  }
  
 }
 
}
