Ultra smooth menu not very 'ease'y

Hello.

I’m trying to create a menu similar to the one on this design company website www.madethought.com. I’m pretty new to flash, I’ve created a couple of websites, I just wanna start making them look smoother and a bit more pro. I tried making a drop down menu using a combo of movie clips, buttons and shape tweens (with ease applied), but so far my attemts are no where near as elasticky, bouncy, smooth like the menu on the madethought site. I also had a look into using actionscript working through an ‘ease’ tutorial (http://www.kirupa.com/developer/flash8/easing.htm), but this tutorial shows you how to ease movement on the x axes rather than applying ease to a shape tween.

I would really, really, really appreciate any help on creating bouncy, smooth menus!!!

cheers, BEET
