Saw this while looking to help someone.

A css style of navigation where the png images in nav expand on mouse over. Fisheye.

I have coded it to work on one of my themes. Theme Cool Blue .

The code was found at ndesign-studio .

For those that want something different on your site check it out.
If your a noob coder, like me, it doesnt really take long.

I have the links and text for buttons in nuke-evo ATO.
IE7 has a problem with nav size.
Most likely because I moved nav down from its org top position.
