With this plugin you can show the tags in your tagcloud that are used in a post. It only works on single post pages.

Tags that are used in the current post get an extra class: ‘current-tag’. You can use this to change the style of these tags and show them to your visitors.

Setting it up

The plugin has no options page. Drop the php-file in wp-content/plugins and activate it. Now change your stylesheet and add some magic for

li#tag_cloud a.current-tag

Or you could get creative in jQuery by selecting them and drawing big arrows pointing to the post title. Thoughts how you can use it are very welcome in the comments. I’m still thinking about how it could behave on other pages, including the front page.
