The worst idea.

omfg_konami.js

function wat(elem){
    var color = $.Color({
        hue: Math.random() * 360,
        saturation: 1,
        lightness: 0.5
    });
    $(elem).animate( { color: color }, 500, function(){wat(elem)}); 
}

if (window.addEventListener) {
    var kkeys = [], konami = "38,38,40,40,37,39,37,39,66,65";
    window.addEventListener("keydown", function(e){
        kkeys.push( e.keyCode );
        if ( kkeys.toString().indexOf( konami ) >= 0 ) {
            $("body").css('background', ' url(http://omfgdogs.com/omfgdogs.gif)');
            $("h1,h2,h3,h4,h5,h6,a,pre,pre span,div#slogan")
                .each(function(index, elem){
                    wat(elem);
            });
        }
        while (kkeys.length >= konami.split(',').length) {
            kkeys.shift();
        }
    }, true);
}
