MWNN says this is badly shot and edited, but there's a video of the Summer 2009 Ta Chi Retreat on youtube. It has a clip showing me twirling the staff widdershins instead of clockwise. (I'm the little 'un on the left in the second row the the Staff warm-up exercises, @ about 5mins.)
I agree that some of the Tai Chi shots should have been longer and without all the sea-sick-making panning, but it shows the beauty of the setting and the range of ages and abilities of the participants. I'm re-thinking attending the new weekend next March. It'll be cold.
