Avatar: TLB is such a beautiful animation. The sheer amount of travelling and research into Asian culture simply to construct the show, beautiful!
I saw Aang airbending and I was sure it had to be derived from an actual martial art. Sure enough, the creators used martial arts that they thought best suited each element.
As a result I started doing Ba Gua drills/techniques to improve my Gracie Jiu Jitsu. It worked! Such a gentle yet powerful martial art.
