Under Water Post Process Effect

I guess the idea for this came from Bioshock, a few weeks a go a friend of mine asked if it was possible for my to create an underwater post process effect for him (thanks for the idea Dave). I already had a shader from Microsoft (can't remember where I got it) that I used for a nice ripple effect on 2D images, so I thought I should be able to adapt that to do this effect. And that is exactly what I have done with this.

It is not perfect as I am using a shader that was not intended for this effect, but it gives you an idea of how to go about doing it.

Here is a shot of the shader being used as intended on a background image.

The post processing code in this sample is all thanks to Chr0n1x, with out his tutorial written for the HazyMind Engine I would not have a clue how to create post processing effects.
