Portfolio Project Page: CSS for making the arrows leading also to first/last Project "endlessly"?

on the bottom of each Portfolio Project page, there are these arrows leading to the next or previous project. But on the first and last project, there is only one arrow.

Is [it possible to] have these arrows go "endlessly" through the projects?

As you say, when a user reaches the last portfolio subpage, the right arrow is hidden. This is an important visual stimulus, indicating to the user that they have reached the end of the results. It is also a recognised industry pattern, helping users to feel 'at home' on the website.

Although a developer could write JavaScript to add links (to allow continuous looping), I don't think this would improve the user's experience and so I don't recommend it.
