automaton

This plugin creates a tag cloud that has, per tag, an indication of that tag’s size, between brackets right after the tag and within the anchor text. This is for the benefit of screenreaders, who will read this information aloud. 
This additional text is hidden from screenreaders by an included styling class. I am working on an option to include your own.
I’d like to add some localization options, but I have insufficient PHP knowledge to implement that. If you’d like to help out, please let me know at http://www.automaton.be/contact/

Accessible Tag Cloud

Accessible replacement for the default tag cloud

WPKube

The plugin renders a tag cloud using a professionally designed tag image as a background.
The plugin’s tag cloud is completely responsive and is correctly rendered in all browsers.
The primary application of this feature is through the “Cool Tag Cloud” widget, but you can also use the shortcode [cool_tag_cloud] to display the tag cloud anywhere where shortcodes are supported.
Here is the list of parameters that can be used with the shortcode, each with its own set of potential values (which are separated by the | symbol):
<ul>
<li><code>style="default|silver|green|red|blue|brown|purple|cyan|lime|black"</code></li>
<li><code>font_family="Arial, Helvetica, sans-serif"</code></li>
<li><code>smallest="10"</code></li>
<li><code>largest="10"</code></li>
<li><code>align="left|right"</code></li>
<li><code>font_weight="normal|bold"</code></li>
<li><code>text_transform="none|uppercase|lowercase|capitalize"</code></li>
<li><code>number="20"</code></li>
<li><code>order_by="name|count"</code></li>
<li><code>order="ASC|DESC|RAND"</code></li>
<li><code>taxonomy="post_tag"</code></li>
<li><code>nofollow="yes|no"</code></li>
<li><code>animation="yes|no"</code></li>
<li><code>on_single_display="global|local"</code></li>
<li><code>on_archive_display="all|children|siblings|descendants"</code></li>
<li><code>exclude="1,2,3"</code></li>
<li><code>include="1,2,3"</code></li>
</ul>

Cool Tag Cloud

This came as a blessing when I had written some custom code to show a custom Taxonomy cloud on sidebar. The options to customize are so cool, and I love the option to either show the taxonomy related to a post on a Single post page or all tags, that makes it so versatile. Thanks so much to the author.
