Yes, the underlying trig is actually fun when you're doing something destructive with it!
Similar trig functions were the genesis the the Dick O'Kane and John P Cromwell attacks. You should see all Nisgeis' and my e-mails back and forth in the development of that one! It all started out with a deceptively simple (evil) drawing he sent me one day, asking if there could be a rule of thumb attack similar to Dick O'Kane for that situation.
Here came the proverbial five pages of trigonometry! And at the end of that, a short list of rules for that precise angle setup, so that the user of the method didn't need my five pages of trig!
It's funny that when I was in school I was intimidated by math and now it almost qualifies as a hobby. How far the "mighty" have fallen!
