How would I run this code over and over?

I have this set of code that fades in and out. What I need is to repeat it over and over, endlessly as long as the page is open.

$(document).ready(function() {
    $('.one').fadeTo(500, 1);
    $('.one').fadeOut(500, 0, function(){
        $('.two').fadeTo(500, 1);
        $('.two').fadeOut(500, 0, function(){
            $('.three').fadeTo(500, 1);
            $('.three').fadeOut(500, 0, function(){
                $('.four').fadeTo(500, 1);
                $('.four').fadeOut(500, 0, function(){
                    $('.five').fadeTo(500, 1);
                    $('.five').fadeOut(500, 0, function(){
                        $('.six').fadeTo(500, 1);
                        $('.six').fadeOut(500,0);
                    }); 
                });
            });
        });
    });   
});

$(document).ready(main); 

I was thinkging of setInterval, which works, but the whole loop is 60 seconds long and setInterval doesn't start at 0 but at the time that is set.

In this case I would have to set the interval at 60000 and then wait one whole minute before the loop starts.

Is there a simpler way to start the function again? Or is there a way to start the setInterval at 0?
