EKShakeAnimation is a litte class for displaying "shaky animations" (yeah, right?). It is inspired by failing to log in on my Mac. The class is made for the Cappuccino framework.

Simply import the file in your application's AppController or any other class:
@import "EKShakeAnimation.j"
Usage is simple. Just fire it up and feed it with any view you want:
var animation = [[EKShakeAnimation alloc] initWithView:someCoolView];
