Create views from combination of various vocabularies' terms
You can have nice block displaying all terms coming from your mentioned vocab by help of Cumulus.

Though its in DEV mode but it works fine. This requires module Tagadelic to be enabled first.

You can create a cumulus block by visiting admin/structure/block/add-cumulus-block, where you can mention name of the block &amp; setting for it such as Vocabulary IDs to be included, Number of tags to display, Width, Height etc..
