Combining Taiji, Xingyi and Bagua

Well, the guys over at "The Rum-Soaked Fist" sure have a good eye for picking out exceptional masters of the internal arts. This one is on a thread highlighted above.
The guy is a Japanese Master practicing Chinese Internal Arts, which is a curiosity.
A clip at the forum linked above shows his form movement, clearly exhibiting elements of Taiji, Xingyi and Bagua. This clip is of principles in application. Sure, it's a fairly static attack for this demo, but the Master is good at showing how some movement in the form is actually done in a different way in application.
For instance, in bagua we walk in a circle performing a posture or movement. Now, in application you do not attempt to walk around your attacker, it is not possible. Instead, you use the principle in the form that turns the opponent's body. Also note that when he uses the slapping strikes, he is hitting vital or pressure point areas. Downward into the bowels and bladder in front, and coming up into the occipital protuberance or gallbladder 20 on the back of the head. These strikes don't look like a power punch, but they would overload the attackers central nervous system and that last shot to the head would be a knockout.
People who practice Chinese Internal Arts will recognize Slant Flying, White Crane Spreads Wings, High Pat On Horse, The Bagua circling or Xingyi angle-stepping as in Pao Chuan.
Good stuff! The guys on the RSF forum suggest the Japanese call this "Taikiken".
