I have been surfing the net and I ran across an AWESOME site (I thought anyway) well inside this site they had a menu that I thought looked great. and just attempting to gain a new skill I was wondering how the did the TV Snow in light (I guess u call it that) effect. 
Thats an image of the Menu coming out you can find the site at

I have no idea how they did this. My Questions are like
Did they use images and tweening or what?
or did they accomplish it with Actionscript
