My friend online was talking about an isometric game so I made this yesterday:
Maybe one of you is working on an isometric game and always wondered if realistic waves were possible. I just used a 128x128 height map for the wave and interpolated between another height map which I generated using the flashes perlin noise. I also used a sin wave for the well… wave effect 
I have other work at the moment, but I’m sure someone knows how to render bitmaps along points if their dedicated toward their project. All I rendered though was points of different color. If you have CS3 you can change the amplitudes of the wave’s sine and other properties. In the example I set the perlin noise’s effect rather low, but you can see it on the shoreline.
Have fun!
