Tim and Jennifer lectured at the University of Pennsylvania on April 2nd, 2007. The class was on perception of public spaces, and we lectured on how virtual worlds were changing the perceptions people have of public space. Additionally, we talked about how avatars relate to space in the virtual realm.
