MenuWiper is a system extension that causes the Finder’s menu bar to slide down the screen, erasing it, as the Finder exits. The menu bar then glides back down from the top of the screen (without any menus in it), and the name of the application being launched slides onto the screen, from right to left, winding up in the center of the screen (instead of just appearing in the center of the screen).
It serves absolutely no useful purpose whatsoever, but it’s fun to watch.
