Random Tags Cloud displays your tags by selecting randomly. Of course, you can customize other tag cloud's settings.
Random Tag Cloud allows you to display your site's tags. It works just like a regular tags cloud, but you can customize it. If you set, it gets your tags by selecting randomly. Of course, you can set other settings; font sizes, number of tags to display, how to order etc. Now, you can add a link to your tags archive page by writing its ID. It adds a 'Show All Tags' link.
