Adding randomization to simple testimonial rotator

Question

There was an awesome, super-minimal testimonial rotator that I found here, but I'm curious as to how I might get it to simply randomize the results. Here's the rotator as it now functions:

$('.testimonials div:first').show();

setInterval(function(){ 
    $('.testimonials div:first-child')
        .fadeOut(1000)
        .next('div')
        .delay(1000)
        .fadeIn(1000)
        .end()
        .appendTo('.testimonials') 
},3000);

Answer 1

Try this:

var $items = $('.testimonials .item');

function getRandomItem(){
    return $items.eq(Math.floor($items.length * Math.random()));
}

getRandomItem().show();

setInterval(function(){ 
    var $outgoing = $items.filter(':visible');
    var $incoming = getRandomItem();
    $outgoing.fadeOut(1000, function(){
        $incoming.fadeIn(1000);
    });
}, 3000);
