jRumble is a jQuery plugin that rumbles, vibrates, shakes, and rotates any element you choose. It’s great to use as a hover effect or a way to direct attention to an element. You can control the X, Y, and rotation range, the speed, and event trigger for the rumble. However, jRumble is currently a little buggy in Internet Explorer. A rumbleSpeed of 0 seems to break the rumble. Also, there is currently no rotation on any objects in IE. This plugin is free to use!
