TagCloud

module_name
tagclouds
Description

Provides a block with a tag cloud of chosen taxonomy term. Works but a bit buggy, e.g. UI taxonomy setting reverts to 'tags'.  Requires clearing the cache to update (including changing any settings).  Choice of numbers after each tag to indicate quality, or 'wordcloud' style with varying sizes (will need you to modify your CSS to add some spacing between words).
