I think that it takes a good deal of skill of pull of these tricks, lot's of practice and time and effort perfecting the skills of the trick, so that would be...kung fu?
Anyway, the real downside of such tricks is that for those who are uninitiated, i.e. the regular civies who do not do KF, that is ALL they associate chi kung with. They don't quite get the subtleties and think that if you do Chi Kung you become Neo.
Same reason why Wushu-fied Hollywood-fu is bad - leads to unrealistic expectations of fighting and martial arts.
...don't think you are, know you are...
