(Background of Lawrence Lessig(courtesy of Wikipedia))

Lawrence Lessig is an American academic. He is a professor of law at Stanford Law School and founder of its Center for Internet and Society. Lessig foundedCreative Commons and is a board member of the Electronic Frontier Foundation and of theSoftware Freedom Law Center. He is best known as a proponent of reduced legal restrictions on copyright, trademark and radio frequency spectrum, particularly in technology applications. He has a very funky but effective style when he gives his class lectures with his electronic keynote presentations. He narrates this presentations will showing keywords of his narration that actually helps one focus better on what he is saying. I find it pretty trippy at least.

Professor Lessig's own description of this video of his - "A call on PA voters to become superdelegates, and bring this cycle to an end."
