"acts_as_audited" - anyone have code for displaying the YAML stored audit-changes?

Hi,

Does anyone have the code to read in the activeRBAC changes (stored in yaml) and display them in a view they could post? For a given record in the audits table for example, and the yaml that is stored in the changes column. I have read in the yaml from the changes column for a given audit table entry, but just now wondering how to consume this and display it (my first time with YAML)

Thanks
Greg
