Codrops has shared a tutorial about how to create a bubbly navigation with jQuery. The idea is to have some round navigation icons that release a bubble when hovering over them. They will use the jQuery Easing Plugin for a even nicer effect.
However, if you are an IE user you might have noticed that the bubble looks kind of weird without CSS3 support. He has figured that has something to do with the transparency of the image and the animation, but there is no solution yet. Please use Google Chrome to view the demo for now.
