Hi!

You are on the right track! Moving the data at 2 nodes per step, stops the
height from adding up unrealistically? Fine! I wonder though.. Do your
system works so that all horisontal movements has a steady speed?  Imagine
the wind direction is -1*x  and you have a rock somewhere that blocks that
movement. This will cause waves to bounce off in different directions, and
some waves will go directly the opposite way  ( 1*x )... In your system,
will they continue in that direction with the same speed and fade out?  In
real life, I suppose they will fade and change speed, to eventually end up
going at -1*x  again.

This may not be necessary to simulate, though, as the effect might be
subtle?

Fortunately, your system does not slow down with the use of many wave
emitters.

Sounds very interesting!
