<p>There are times when you’d like to have a certain type of post appear in a widget for use in your sidebar or (in some themes) your header or footer.</p>
<p>I used this to display a random senryu on each page, but it will work equally well for any group of reasonably small posts.</p>
<p>There is the option to include the title of the post, the title of the widget, both titles, or neither.</p>
<p>If you want you can add a bunch of widgets, each showing up to five random posts from a different category.</p>


Random One Cat Widget

This Widget shows up to five random posts from a given category
