Fading out everything except the element that's being pointed by the mouse

Question

Sort of like a "Lightbox 2" effect but only on the elements pointed by a mouse. I don't even know how to start. Any advice would be awesome, thanks.

Answer 1

Like this:

$(function() {
    $('*').fadeTo('fast',0.5).hover(function() {
        $(this).fadeTo('fast',1);
    }, function() {
        $(this).fadeTo('fast',0.5);
    });
});
