Dealing with sensitive numbers in a top secret Excel spreadsheet? Reading classified documents that you don't want people to see? Or most likely, exploring the more salacious parts of the internet and don't want to be thought of as a creep? Follow these instructions that show you how to create an awesome secret monitor only you can see.
Brusspup, the illusions wizard on YouTube, basically stripped the polarising filter that comes standard on top of any monitor to make the content that appears on the screen invisible (or rather, unreadable). To make the screen readable, Brusspup then made special glasses with the same polarising filter to decipher the blankness. That way, whatever's on the screen is made for your eyes only. Way better than dark privacy screen filters!
You can be a weirdo by looking at weird stuff on the internet for all to see or you can be a weirdo by looking at a blank white screen for all to see. [Brusspup]
