Studying “virtual worlds” in school

My new grad school program is called the Interactive Telecommunications Program, or ITP. ITP is within the Tisch School of the Arts at NYU. This is actually my second Master’s degree. One of my major interests is in studying dance and movement, and technology. This semester I’ll be taking a class on Virtual Worlds. I think I should spend some time researching virtual performance, and I’m interested in discovering the similarities and differences of virtual worlds and other studies in Computer-Supported Cooperative Work.
