Falling Grid Transition

Hi Guys,

I am a bit stuck with reversing the rising grid transition from senocular and wonder if any of you would be able to give me some advice. I am trying to get the grid from this example (http://www.senocular.com/flash/source.php?id=0.182) to reveal the image by the squares falling into place rather than flying out to reveal the next image. I have some actionscript knowledge but am really stuck with this.

Any help would be much appreciated.

Many Thanks
