The Physics of Angry Birds

I have seen plenty of article on the physics employed in the wildly-popular app game "Angry Birds". I came across another one here that describes the kinematics and collisions that any intro physics student can understand.

I think that the kinematics part is rather trivial, but the subsequent collisions and "destruction" that follows can be quite complicated. That would have been a more interesting part that should be discussed in depth.
