If you'd like to attend college classes over the Internet at a wide variety of prestigious colleges, consider visiting Academic Earth. According to the about page,

We are building a user-friendly educational ecosystem that will give internet users around the world the ability to easily find, interact with, and learn from full video courses and lectures from the world’s leading scholars. Our goal is to bring the best content together in one place and create an environment in which that content is remarkably easy to use and where user contributions make existing content increasingly valuable.

The participating universities include Berkeley, Harvard, MIT, Princeton, Stanford, UCLA, and Yale. I just finished watching an informative lecture on "The Origins of the Financial Mess." I'm wondering what I'm going to view next. Maybe I'll watch some more of Shelly Kagan's 26-part series on the topic of "Death."
