Random Post Box is a plugin that lets you place a box anywhere on your blog, with template tag or shortcode, and 
load random posts with an interval and fade effect. It uses jQuery (Ajax) which means that the content is loaded without 
loading the rest of the page. The timings can be set in the admin options-panel.
The template tag is <code><?php random_post_box(); ?></code>. You can also use the shortcode <code>[random-post-box]</code> in a page or post.

This plugin was built to add a “Random” Product Sorting Order to WooCommerce with working pagination.
Other solutions I found that added a “Random” Product Sorting Order did not preserve pagination.
This plugin will sort your WooCommerce Products in random order. A random sort has a transient life of one hour. (In version 0.9.1, the duration is not a settable option. It is fixed at one hour.) Every hour a new random sort is generated. Pagination works as expected, meaning each WooCommerce Product will be diplayed once and no more than once.
This plugin requires the WooCommerce plugin.
