I enjoyed one of his presentations about a year ago. He’s as lucid a speaker as he is thinker. He covered some topics that are in his books, and a few advanced ones besides. He’s also a sculptor and he made a small side-trip into presenting some his work in that area. If you have his books, though, you can get all the same insights from them. If you don’t have his books, note that you get all four of them included at the workshop!
