Continuous Looping Page (Not Infinite Scroll)

Question

I\'m looking for resources that create scrolling functions like the ones found on these sites:
Outpost Journal
Unfold

Once the scroll bar hits the bottom

Forked from @clankill3r's answer, create two copy of body, prepend and append to the original body, then you can scroll the page in two direction endless.

$('document').ready(function() {

    var origDocHeight = document.body.offsetHeight;

    var clone=$("body").contents().clone();
    clone.appendTo("body");
    clone.prependTo("body");

    $(document).scroll(function(){ 

        var scrollWindowPos = $(document).scrollTop(); 

        if(scrollWindowPos >= origDocHeight ) { 
            $(document).scrollTop(0); 
        }
        if(scrollWindowPos <= 0 ) { 
             $(document).scrollTop(origDocHeight); 
         }        
    });
});
