$(function () {
    function isScrolledIntoView($elem) {
        var docViewTop = $(window).scrollTop();
        var docViewBottom = docViewTop + $(window).height();
        var elemTop = $elem.offset().top;
        var elemBottom = elemTop + $elem.height();
        return ((elemBottom <= docViewBottom) && (elemTop >= docViewTop));
    }

    function count($this) {
        var current = parseInt($this.html(), 10);
        if (isScrolledIntoView($this) && !$this.data("isCounting") && current < $this.data('count')) {
            $this.html(++current);
            $this.data("isCounting", true);
            setTimeout(function () {
                $this.data("isCounting", false);
                count($this);
            }, 50);
