Semi-transparent rollover effect using jQuery

Background has a gradient effect, so you can see that the glowing borders flow smoothly on rollover. Try that with a gif!

Here's the code which loads the images:

$(function() {
	SSS.preloadimages("btn_", "home_on.png",
	  "store_on.png", "stories_on.png", 
	  "lessons_on.png", "company_on.png",
	  "careers_on.png", "contact_on.png");
	SSS.menuinit();
});
