Based on the original Random Redirect, this plugin enables efficient, easy random redirection to a post. Supports setting a category for all random redirects, shortcodes to generate URLs that can override the default category, and setting your own redirector URL. Designed to scale to handle high-traffic websites with thousands of posts by using a more efficient strategy than most other redirection plugins employ.

This plugin was developed to display excerpts from random posts in a category. jQuery is used for fading the plugin in and out. It’s a great way for displaying testimonials of clients or just giving a snapshot of content from your site.
Shortcode added as of version 1.4
The most basic use is: <code>[reFader]</code> this will use the default options. 
Here is an example of all the options in use 
 [reFader title=”Random Excerpts” cat=”23″ type=”post” amount=”5″ length=”50″ duration=”5000″ linked=”no” url=”http://www.jackreichert.com/”]
This will show 5 (amount) posts (type) from category #23 (cat). It will show 50 (length) words from each post and fade out/in every 5 seconds (duration). It will not link each title to the corresponding post, but it will link all the titles to this plugins page (url).

Random Excerpts Fader
