Ghostzilla is a web browser designed to let you surf without others around you knowing that you are surfing. The browser appears hosted in some other application, with text grayed and images place-held, for minimal read-over-the-shoulder-ability. Mouse gestures control its coming and going.

While it is unfortunate that we have either (a) people lying to their bosses about how they spend their time, or (b) bosses that have unreasonable expectations of how their workers spend their time, I think it is cool that someone hacked Mozilla to come up with a clever technical solution to the problem.
