Actually yes, have you ever looked into (chinese) white crane kung fu, I have never seen it in practice but think you guys probably do almost the exact same stuff based on watching you, and what little I read about them.
There was one movement you guys were doing which looked just like a segment from the first form in wing chun, ( which is crane influenced), but done with different energy, and probably for a different reason.
Another movement you did was similar to a xing yi crane movement ( that I need to practice) watching you guys gave me an idea on how to do it better,
but again with a different energy/intent.
Finally another movement 2 people were working on looked similar to tai chi push hands , and also certain snake movements.
Generally speaking nice people.
