Item Navigation Loop was created by Joe Campbell

How can I modify the item override file to provide a previous and next for the first and last item in a category. (otherwise each would be none)

Here's the logic:

If first category item render last item as previous link

If last category item display first item as next link

Basically you want to create an infinite loop, right?
That would mean, either hacking K2's model or using an extension.
If you only want to use overrides, then you have to manually query the db and display that item.

Yes, an infinite loop.

I would prefer to not hack, but querying the DB would impact performance, right?

Not really, provided that you use caching of course.
Since a query would only be made when only two circumstances are met, chances are that the impact will be minimal.

I am not using caching.

Can this be a feature added to K2v3 (Category > Item Navigation > Loop) ???

I think it makes sense for most instances - plus I believe would be beneficial from an SEO standpoint as well.

Thanks for the link @JaviMata but I am looking to use the built in Item Navigation.

Perhaps this example will help illustrate my point:

This is the LAST item (NO Next item link): I want it to display a next (link to first item in category)
demo.nuevvo.com/sites/j3x/janaro/index.php?option=com_k2&view=item&id=31:2001-a-space-odyssey&Itemid=171

This is the FIRST item (NO Previous item link): I want it to display a previous (link to last item in category)
demo.nuevvo.com/sites/j3x/janaro/index.php?option=com_k2&view=item&id=13:dear-white-people&Itemid=171
