How it works is pretty simple. The monitor’s polarizing filter is removed, causing the screen to glow a bright white. The filter is replaced by polarized lenses in a pair of glasses which enable the wearer to view the computer screen as normal, while hiding the content to anyone viewing the screen unaided.
It doesn’t appear to be a difficult project. And while the result is pretty neat, I wouldn’t want to be tethered to a pair of glasses just to use my computer. Also, I have no idea what other issues are created by removing the polarizing filter of the monitor, including possible health risks(?).
