Any videos/presentations explaining the concepts of the Model View Controller (MVC) pattern?

I was wondering if there are any videos (eg. Google Tech Talks) presenting the MVC pattern.

If so, I would highly appreciate any so开发者_JAVA百科urces you can provide.

Alternatively, what reading material (preferably online) would you recommend to fully understand the pattern?

Thanks in advance.

Also, are you a registered dev for apple? cause they have videos for download. (Try the 'iPhone Application Development - Getting Started' video at about 5:50 in. )
