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 the simulation for a massive tsunami.
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.
0,0 is the center, bounds are -1 to 1. 0.1 radius is a reasonable spike, 1 radius is a huge swell. 1 strength is really big. 10 is ridiculous. Try negative numbers too!
