How can I display a list of related vocabulary terms in a block next to my content?

I am in the process of developing a job site and I currently have all job types listed as terms which are searchable and list viewable by users. I would however like to have a block that lists five or so related job types when a user is viewing a specific job. If these were set up by simply specifying 'related terms' in the advanced options when creating a term this would be even more favourable.

I have searched through Drupal and other forums to try and find an answer to what I am after but at present I can not locate anything that will do that job I am after

Has anyone used or created something along these lines? I would appreciate your thoughts

Many thanks
