Like Angry Birds? Of course you do! Why not show off your love for the pig killing birds by pimping your iPhone with a fancy Angry Birds case?
The cases, made by Gear4, are available in Red Bird, Yellow Bird (my favorite), and the evil Pig King. The case will set you back $35 and while they will not directly improve your Angry Bird skills, they will probably motivate you to be the best pig killer ever!
