It's too bad that they didn't video it professionally so we could have seen the gems better, and because half the time we were looking at the ceiling instead of the screen.
I'm glad he used Bear Williams' work for his lecture, and I believe we have Bear's findings on the forum in an article or two, but not in video form so thanks for posting it for us OS.
