Exactly. I can absolutely relate to the complex rhythms. There seems to be some sort of continuity about this movement, like the energy is flowing and bouncing inside the body, then when it encounters a blockage it shifts course like the roomba vacuum cleaner. Also, there's a sense of beginning and end, meaning that if I wanted to stop the movement, timing is important (kind of like when you have to stop listening to a song before it ends -I always try to at least wait till the end of a musical phrase).

Something else that occurs quite often is very fast and precise hand movements, much like in the staged fights from old straight-to-video kung-fu movies.
