Mirror on Computer

I took a new position at the university in August. For Christmas 2011, I came across these mirrors in the automotive section of Walmart. I bought one for myself and two for coworkers. My work area now is set up in a way that the mirror on the computer base isn’t the best place for the mirror. I have moved it to a wall that allows me to see behind me when back is to the doorway.

Where could you use a mirror like this?
Or would it make a good stocking stuffer for someone?
