Flash Actionscript Dynamic Water Ripple

Question

I was wondering if/how I can use this effect http://www.flash-filter.net/rain-drop-water-effect-download.phtml, or similar in Flash but instead of having the ripples follow the mouse, follow movie clips. I have a boat MC that I want to simulate moving through water.

Answer 1

I wrote a similar water ripple effect, which also includes shading to make the ripples stand out better, using pixelbender. You can get the source here. It shouldn't be too hard to adapt it to your own purposes.
