has anyone used the "motion trails" add-on?

I was browsing around and ran across an add-on called “motion trails”. I recall seeing this a long while ago. Does anyone use it? Does it work well? What are your thoughts if you do use it?

Basically is it worth installing and trying out?

Here is the link to the add-on. The page includes a video.
