here an unusual clip from a german underground - a good lü for me:http://www.snotr.com/video/994
Sorry no much martial arts action but it worked so well. The guy diverted the attacking strength and let the opponent fall into the emptiness. May be it is not traditional Taichi but anyway the guy got the spirit of lü.
P.S. I do not think it is made up - if you can listen to the german language it sounds quite spontanous
