Kanye West's cousin, Devo Harris (who also goes by the name "Devo Springfield"), recently launched an interactive video company called "Adventr" (pronounced like the word "Adventure"). The site has a demo in which John Legend gives the user a simple, interactive piano lesson, which is pretty cool.
Harris has an MBA from Columbia Business School.
