A production company from England saw a video that I had posted on
YouTube and came out to do a shoot last February. Of course, the weather wasn't
cooperative that time of year, but they spiced in footage from my video. Still
not a very good explanation of the mechanism-of-formation and they get the
rotation wrong. Maybe have to bounce this one off of Osoba next time I see him.
