Underwater Scene Images
I took some screengrabs of the underwater scene in action, but they don't look as good as they should due to my RenderMonkey being slightly screwed. Plus they don't really do justice to the animation, which you have to see to appreciate. Which, luckily, you can right here.
If the angles look a bit weird it's because trying to use the camera in RenderMonkey is like trying to keep hold of a greased pig. Which is not something I've actually done, but I've been told it's pretty hard. However, I do think it makes them look dynamic and action filled, but that's just me.
