This is not a UFO helps to detect screen/monitor ghosting.

Screen ghosting is an annoying issue that generally occurs if there are several fast-moving images on your screen or when you happen to move your mouse quickly. There will be trails coming off the images like a ghost. These traces can be distracting. It occurs when the image is refreshed, and the screen pixels cannot change fast enough, giving you the ghost trails.

This is not a UFO will be useful for checking out a new or used monitor for issues like the slow response time with some LCD screens, for instance. This little app simulates the movement allowing you to visualize any slow response from your monitor.
