Casper Cloaking Technology, Designtex
This 100 percent polyester film, specified for glass walls, can seemingly make your presentation...disappear. Using Designtex's proprietary technology, the architectural film redirects the rays of LED lights emitted from a digital screen so that it disrupts the image—making it look as if the screen is black from an exterior point of view. The technology could be used for information-sensitive meetings in open plan offices that don't wish to compromise on transparency. Casper is applied onto the inner side of a glass wall, and can be embellished through the application of a second, printed film (available in 15 patterns) on the outer side of the wall. designtex.com
