It's really simple. Load a setting (!) and then change the values. The camera control is the usual one I think.

@Emre: I was wondering how an object like a boat or floating wood would have to be positioned that I looks realistic.
Basically, how can I find the hight of the waves at a specific point?
After that I guess that getting multiple points along the object and the adjusting the angle to the wave form would have to work...
