Thanks to taiwandeutscher for the mention.
Willow,
I would suggest checking out the info I have over at my blog in the CPL taiji section:
CPL taiji
There's quite a few technical posts on various aspects of CPL's taiji. I will be adding much more this year. I will also soon be starting a study of his bagua and xingyi.
I would also highly suggest that you get a copy of his taiji book. There's lots of info about him, the form is laid out step-by-step, there are applications, and the classics are even included. A real gem of a book.
