Below is information about flash tag clouds and where to download them.
Tag cloud generator for a standard website
This is a generator where you create a tag cloud by loading a website address, or typing keywords manually. It generate a tag cloud to match your specifications. They give you a zip file to download with the files to upload to your server, and an example of the html code to put on your page where you want the tag cloud to appear. They have different styles in which to display your tags http://www.tagcloud-generator.com/demo.php. The tags do not update themselves as you update your site. If you want your tags to stay current you need to update them manually and upload the new files onto your server every so often.

Tag cloud plugin for B2evolution blogs
This link goes to the flash tag cloud by user Sam2kb at the b2evo forums. It is the most recently updated, and highest rated tag cloud available for the b2evo blog. There are three different tag cloud plugins available for the B2evolution blog at the B2evo plugin directory (http://plugins.b2evolution.net/). This plugin is simple to install, it is the standard b2evo plugin installation. You upload the plugin to your server, install it and set options in backoffice, then add the tag cloud widget where you want it to appear on your blog. The options for it allow you to control the size of text, rotation speed, and other parameters. The tags automatically update with new keywords as blog entries are posted.
(See example on the sidebar of my blog under the title tag cloud; https://web420.com/blog/blog5.php )
Tag cloud plugin for WordPress blogs
There are numerous tag clouds designed for WordPress blogs. If you don’t like the tag cloud I suggest search Google and I am sure you will be able to find one you like. I think this is the best because it is one of the nicest looking tag clouds around, easy to install, and customizable. One thing I don’t like about it is that you cannot control the text size, it is automatically set based on the height and width settings. Tags do automatically update as new posts are written.
