I took some screen captures of the event. What I like about Lesley's presentations about Cybergogy are that they are informative from the perspective of thinking about teaching in a 3D environment but that they also incorporate aspects not possible in the 2D world. For example, as she discusses her the model, she rezz's items right before the audience in 3D.
By the end of the presentation, you can see the model in 3D. You can walk around it, experience it and fly around to check out all aspects of the model. Much more vivid and interactive than a 2D version of the model. It shows all the nuances of the relationships.
If you want to see a video of a presentation where Lesley rezz's items, check out this presentation called Learning Archetypes as tools of Cybergogy: A structure for eTeaching in Second Life which she presented at the Virtual Worlds Best Practices in Education conference in 2010. You can read what I thought of the conference here (hint, it was awesome.)
