The library provides an iOS-like over-scrolling effect for many Android native views. It also allows for very easy expansion to support custom views.

The core effect classes are loose-decorators of Android views, and are thus decoupled from the actual view classes' implementations. That allows developers to apply the effect over views while keeping them as untampered 'black-boxes'. Namely, it allows for keeping important optimizations such as view-recycling intact.
