Sometimes, in the presence of other people we really want the image on the screen of our computer to see only ourselves. No problem, this desire enforceable. Here is the "magic" LCD Monitor: need to look at it in the special glasses - otherwise you will only see a blank white screen. Recipe for a "miracle" of a genius and technical thought is fairly simple. Release the LCD matrix of the plastic shell, with a sharp knife carve the polarizing film, the solvent carefully wipe the glass panel - and re-assemble the monitor. Then take a 3D-glasses and glass paste on the tape that is extracted from the monitor. Done! Video below
