An Instructables user by the name of dimovi has created a privacy monitor in a most ingenious way. He basically disassembled the monitor, removed the polarizing film and glued a cutout made from this film to an old pair of glasses. Once reassembled, only people with the special glasses can see what’s on the screen while everyone else just sees a white monitor.
Of course, people will think you a little strange for staring at a white screen for hours on end, but that sort of stuff never stopped you before, did it?
There’s a more detailed step by step at the link below.
