The web-watching boss, the overly chatty coworker, the kids sneaking into your home office — nobody should have the jump on you while you're at work. A small convex mirror gives you a better view of who's about to enter your space.
For those with cubicles or workspaces where people can suddenly materialise behind you, the value of a mirror like this $US8 ThinkGeek model is easy to understand. It attaches with Velcro to the side of your monitor, and the angled and shaped mirrors give you the kind of rearview image you're used to in your car. But it was a home office worker who suggested this item to us, as it provided him with a view of whichever household member, likely a young one, was about to sneak into his office space and break his concentration.
The C.H.I.M.P. Rearview Monitor Mirror goes for $US8 on ThinkGeek. There are certainly other desk-friendly convex mirrors out there, and if you know of one, drop it in the comments. Thanks for the tip, Eric!
