It looks like it's just an undocumented Core Image filter applied to the layer.

  Can't you get banned from the application store if you use undocumented ipod features?

    Not if you're Apple, and this is Apple's app that the author is talking about.

      So far, all of the Apple apps on the App Store seem to abide by "the rules". I hope that continues.

    You don't get banned, but your app may be withdrawn until the private API calls are removed

    Usually the app just gets rejected if someone uses an undocumented feature. Jailbreakers or people developing just for fun or using the adhoc or (I think) corporate deployment method don't go through the approval process and therefore can't get banned/rejected. So for people in those situations, it's fun to know how to do it.
