Front End View revisions

Does anyone know if there is a plugin which will allow me (site admin) to allow visitors and site viewers to see changes to posts through time? This is much like the wikimedia feature which allows viewers to view an older version of a page. This is standard in the admin section (at least I use it there). I am just wondering if there is a way which I can let visitors see changes through time.

I have looked (googled an in the WP repo) for a plugin but I am not finding anything like this.

– note: it is possible that I may only want to enable this feature on some posts or pages.
