Load random CSS without page refresh

Do you know how to load a random css without refreshing the page? I would like to load a random style like the one achieved in this thread:

<script>
var link = [];
link[0] = "css/0.css";
link[1] = "css/1.css";
link[2] = "css/2.css";
link[3] = "css/3.css";

$(function() {
    var style = link[Math.floor(Math.random() * link.length )];
    if (document.createStyleSheet){
        document.createStyleSheet(style);
    }else{
        $('<link />',{
            rel :'stylesheet',
            type:'text/css',
            href: style
        }).appendTo('head');
    }
});
</script>

This code works, but is it possible to load another style randomly every 5 seconds without refreshing? Thanks a lot.
