Need similar effect to Tsunami

Hello there,

I am in need of assistance. I have researched High and Low as to how I can incorporate a tsunami effect to this flash page I have set up.

The 4 boxes on the right grow and reveal info/picture when rolled over. My issue is the other boxes are overlapping or become hidden. I would like a similar effect to a tsunami that when say the bottom box is rolled over the other three, shrink and stay outside the boundary of the larger image. Does that make sense?

I am familiar with basic flash and this .fla I threw together to show the client the direction I’m going.

Thanks in advance for the help.
