I just realized push-hands (taichi exercise) would be killer. Essentially, you play in slow-mo and speed up, attempting to push one another off balance, while rolling and flowing with each others movements, and keeping your feet rooted. Chi-sau would be even better perhaps, as you must keep your hands "stuck" on the other person, as much as possible, to control their movements. The key is not force but grace and energy. I bet I could boggle some minds contact juggling with these cool hacky sacks with internal lights too... So add your own idea while I use Ye Olde Searche Buttonne
