The only minor nit I can come up with is the lack of surface tension. When you pull the ball up through the surface of the water, some of the water should stick to the ball. Maybe the ball is made out of lotus leaves, though.
I'd also expect some more bubbles when violently stirring the pool with the ball.
does this use the navier stokes equations? How are the ripples generated?
Earlier quoted context omitted.
It appears to work on the top but not on the sides
The sides seem to be a cut-away view, not a surface...
Does anyone happen to know what the effect is called that the sky is reflected stronger at shallow angles and whether that is the same effect which makes rough surfaces reflective at very shallow angles?
This is extremely well done. The only minor nit I can come up with is the lack of surface tension.

A particle-based system could simulate the effects you describe (by keeping track of the positions of some large number of water "molecules" and exchanging forces between each pair of particles), however the simulation would be far too costly to run in real-time on typical hardware today. It also has its downsides. With a height-map based representation it is trivial to calculate the normal to the surface of the water, which is necessary for the lighting effects, but with a particle system you would need to reconstruct the surface of the water in an additional step each frame, using something like the marching cubes algorithm.
Fun trick: Pause the simulation with the space bar. Then, take your mouse and drag it on the surface of the water, you will notice it creates ripples but in the paused state. Drag the mouse rapidly back and forth in a very tiny area so that it creates a layered 'ripple' that grows and grows. If you spend about 2 minutes doing this you can make the ripple go like 10 feet high completely off the screen. Then unpause th…
Rather than dragging, just click in the same spot hundreds of times to make a huge tower of water, then unpause to see a single ring of concentric waves and perfect wave reflection/interaction effects.
