For most technical jobs where the employees reside in cubicles, the sight of coworkers gathering in someone's cube to look at their screen is a common occurrence. But said screen is usually running at high-resolution, optimised for viewing by one person: the one sitting in front of it.
I wonder how practical it would be to somehow have a mirror display/projection on the inside of the cubicle wall, right at the entrance. This display would be switched on/off on-demand. Thus when people stop by the cubicle for a discussion, they can comfortably remain standing at the entrance and look/point at the mirror projection on the cubicle wall, instead of awkwardly bending and stretching their necks forward to get a closer look at the cubicle resident's screen
