WordPress default theme, TwentyEleven , has a built-in showcase mode that is displaying a set a slides (composed of sticky posts) at the top of a page. This mode can be activated by creating a static page and set its Template page attribute to Showcase Template  .

The problem with this mode to me was the lack of an auto-advance feature that will cycle through the slides every X seconds. Luckily I found a way to automate implement this with some lines of JavaScript:

<script charset="utf-8" type="text/javascript">
 // Auto-advance the showcase slider
  // Source: https://pastebin.com/s6JEthVi
    var change_every = 5; // The number of seconds that the slider will auto-advance in
    var current = 1;
    function auto_advance(){
      if(current == -1) return false;
      jQuery('.feature-slider a').eq(current % jQuery('.feature-slider a').length).trigger('click', [true]);
    setInterval(function(){auto_advance()}, change_every * 1000);

All you have to do is to embed this snippet of code within your home page. It could either be in the static page you use as a showcase template or in a showcase widget. The latter is the exact same method I used earlier that year to customize CSS in WordPress without messing with the original code  .

And of course this code is currently live at the front page of that very blog.
