You remember right :)
It is just tricky to simulate it... maybe a slightly translated version of
the function generating the waves?
But while foam forms at wave crest, it vanishes at the back of the wave as
the bubbles make their way to the surface.
I have to say I choosed crackle pattern to make a sea breaking on the shore
with swirls and upwells and not for open sea.
