BubbleUP jQuery Plugin is a fun and easy plugin to get you started in jQuery. The effect is a nice starting point for learning the basics and many of the steps involved in creating other more intricate plugins you will make in the future.

With BubbleUP, images in a list will enlarge with a smooth animation when you move your mouse over it. Then, if you move the mouse out, it will reset to the original size with the same smooth animation. It has been tested on IE 7, Opera 10, Firefox 3.5, Safari 4, and Chrome 5 Beta.
