I'm not sure what do you mean by content rotation
ie if you want that every single time people visits your site they see different content:
Code:
<ul>
<?php
$args = array( 'numberposts' => 5, 'orderby' => 'rand' );
$rand_posts = get_posts( $args );
foreach( $rand_posts as $post ) : ?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endforeach; ?>
</ul>
if you want that every time you add content that content is shown (like in latest added scenes) you don't need anything at all, that's the default for most if not all CMS, including WP
if you mean something like
