A long time item on my todo list is to make a good water simulation. Never tried it because it seemed to difficult in my mind. Today i made a first start on getting it done. In this first test i make use of graphics.lineTo to draw lines and bitmapdata.draw() to draw them into a bitmapdata. I do a little blur along the way and i pixelDissolve the bitmapdata. This is then used as a displacementMapFilter for the image.

Here’s the result with only the displacementMap showing.

And here’s the result with the image and the displacementMap set:.
Move your mouse over de image.
