Casper Cloaking Technology was designed for people who need confidentiality in their work space or sometimes their home. This product is primarily used in office settings because its design allows you to have an "open feel" look while also disguising your screen. In other words, to someone viewing the display screen from the outside of the treated glass, a computer screen/tv screen appears black, meanwhile to the person on the opposite side (inside a conference room for instance) the screen appears normal.
