Not only have I heard of it, I had the good fortune of studying under the art's founder in Korea. It is not a compilation art. It was developed by a master street fighter. When not fighting, he would live a solitary life and practice what worked, discarding what didn't. He studied animals, and created forms. Everything he taught had been tested in actual combat. His story is trully incredible, I'm sorry I don't have space to tell more of it. His name is In Hwan Chung. He presented me with my Third Dan rank in 1992.
