Does anybody out there have any idea how to create breaking ocean waves? The
part I can't figure out is how to make them curl. Any help would be
appreciated.

not tested at all for now, but an idea:

breaking of waves occurs, whenever a wave runs into flatter area, and
its length changes (increases?/or decreases?, I'm not shure.) therefore.
In PoV code you could probably simulate this, setting up an iso box and
modulating its top surface with two (or more) pigment{onion} functions
of reasonable different frequency.
Making the waves curl at its top will come much more difficult: perhaps
a very slight perturbation (in relation to the wave amplitude), brought
up by noise 3d (or pigment{wrinkles/or crackle? or even granite?) in
combination with
appropriate lightingh/and point of view) will do the job?
