If you flirt with disaster on a daily bases by navigating to inappropriate web pages while at work, well then the web site Vanishd has a solution for you.

Once active, Vanishd lays a work safe webpage or word document on top of the site you are actually interested in, and gives you a small window controlled by your mouse that looks through the top page, and into the page you wanted hidden.

Ok yeah I know that makes absolutely no sense, so instead of trying to explain it to you, how about you just watch this video.
