Tag Clouds

Hi there

I’d like to create a tag cloud for this website http://www.matthewbristol.co.uk/

Just wondering if someone could please advise me the best way to go about it. The plugins I have seen when doing a search only seem to apply to posts rather than pages, but our website contains all pages, no posts.

Also, is it advisable to put a tag cloud on one page, or all pages of a site?

Many thanks for your help in advance.
