« The passionate scientist: Doing Q&A like Neil deGrasse Tyson | Main | Tips for creative success from Pixar »

I watched Lessig's Educause 09 screencast. I think he is using the visual 'track' as a way of helping audience members remember key ideas. For example, his use of the images of Britney Spears and Souza to 'stand for' two ecologies of production - introduced as examples early and then referred to later on that split screen to bring the two 'ecologies' into sharp contrast.

The whole thing is a teaching design, with retention of information and concepts as the aim.
