4. Enable the slideshow.

$('.slideshow').imagesLoaded({ background: true })
.done( function() {
  // hide loader
  $('.loader').addClass('is-loaded');
  
  // init variables
  var slideshow = $(".slideshow"),
    navigation = $(".navigation"),
    navigationItem = $(".navigation-item"),
    detailItem = $(".detail-item"),
    rotation,
    type = '_short';

  // prepare letters
  $('.headline').each(function() {
    $(this).html($(this).text().replace(/([^\x00-\x80]|\w)/g, "<span class='letter'>$&</span>"));
  });

  // prepare navigation and set navigation items on the right place
  navigationItem.each(function(index, elem) {
    TweenMax.set(elem, {
      left: navigation.width() / 2 - navigationItem.width() / 2 - 10,
      rotation: 90 + (index * 360 / navigationItem.length),
      transformOrigin: "50% " + navigation.width() / 2 + "px"
    });
    TweenMax.set($(elem).find('.rotate-holder'), {
      text: String(index * 360 / navigationItem.length)
    });
    TweenMax.set($(elem).find('.background-holder'), {
      rotation: -90 - (index * 360 / navigationItem.length),
    });
  });
  
  // set tween values
  function setTweenValues() {
    rotation = Number($(this).find('.rotate-holder').text());
  }

  // do tween
  function doTween(target) {

    var targetIndex = navigationItem.index(target),
      timeline = new TimelineMax();

    // add/remove class "active" from navigation & detail
    navigationItem.each(function() {
      $(this).removeClass('active');
      if ($(this).index() == $(target).index()) {
        $(this).addClass('active');
      }
    });
    detailItem.each(function() {
      $(this).removeClass('active');
      if ($(this).index() == $(target).index()) {
        $(this).addClass('active');
      }
    });

    timeline
      .to(navigation, 0.6, {
        rotation: -rotation + type,
        transformOrigin: "50% 50%",
        ease: Sine.easeInOut
      })
      .staggerTo(navigationItem.find('.background-holder'), 0.6, {
        cycle: {
          //function that returns a value
          rotation: function(index, element) {
            return -90 - Number($(element).prev('.rotate-holder').text()) + rotation + type;
          }
        },
        transformOrigin: "50% 50%",
        ease: Sine.easeInOut,
      }, 0, '-=0.6')
      .staggerFromTo($('.active').find('.letter'), 0.3, {
        autoAlpha: 0,
        x: -100,
      },
      {
        autoAlpha: 1,
        x: 0,
        ease: Sine.easeInOut,
      }, 0.025, '-=0.3')
      .fromTo($('.active').find('.background'), 0.9, {
        autoAlpha: 0,
        x: -100,
      },
      {
        autoAlpha: 1,
        x: 0,
        ease: Sine.easeInOut,
      }, 0.05, '+=0.3');
  }

  // click/hover on items
  navigationItem.on('mouseenter', setTweenValues);
  navigationItem.on('click', function() { doTween($(this)); })

  // on load show slideshow as well as first "active" navigation/detail item
  TweenMax.to(slideshow, 1, { autoAlpha: 1 });
  TweenMax.to($('.active').find('.letter'), 0.7, { autoAlpha: 1, x: 0 });
  TweenMax.to($('.active').find('.background'), 0.7, { autoAlpha: 1, x: 0 });

});

// fast fix for resize window and refresh view, attention: not use in production, only for demo purposes!
(function () {
var width = window.innerWidth;

window.addEventListener('resize', function () {
  if (window.innerWidth !== width) {
    window.location.reload(true);
  }
});
})();
