Logo Rotativo

• Descrição:

Boa noite, 

Há algum tempo, eu pedi um código para fazer meus banners serem rotativos:

Código:

window.addEventListener('DOMContentLoaded', function() {
    var urls = [
            'http://giant.gfycat.com/SelfreliantRequiredHarvestmouse.gif',
            'http://s4.uploads.im/S8yN7.gif'
        ],
        pics = urls.length,
        logo = document.querySelector('#logo img');

    if (iv(logo) == false) return;
    window.setInterval(function() {
        logo.src = urls[randoms(0, pics - 1)];
    }, 6000);
});

function iv(element) {
    var eap,
        rect = element.getBoundingClientRect(),
        doc = document.documentElement,
        vWidth = window.innerWidth || doc.clientWidth,
        vHeight = window.innerHeight || doc.clientHeight,
        fromPoint = function(x, y) {
            return document.elementFromPoint(x, y)
        },
        contains = "contains" in element ? "contains" : "compareDocumentPosition",
        has = contains == "contains" ? 1 : 0x14;

    if (rect.right < 0 || rect.bottom < 0 || rect.left > vWidth || rect.top > vHeight)
        return false;

    return (
        (eap = fromPoint(rect.left, rect.top)) == element || element[contains](eap) == has || (eap = fromPoint(rect.right, rect.top)) == element || element[contains](eap) == has || (eap = fromPoint(rect.right, rect.bottom)) == element || element[contains](eap) == has || (eap = fromPoint(rect.left, rect.bottom)) == element || element[contains](eap) == has
    );
};

function randoms(min, max) {
    return Math.floor(Math.random() * (max - min + 1)) + min;
}

Gostaria de um novo código, para rotacionar meu logo, no lugar.
