The idea of Magic Wall is to create grand, high impact and convenient announcements.
Example setting: Office
The system memorizes the boss’s face and map it to the Magic Wall.
Every time the boss makes an announcement, the Magic Wall extrudes out into the shape of his face, and the lips/ facial expression of the wall moves according to the tone and words of the boss while he is talking from a different location.
The people can also talk back to the wall and have a conversation with the wall as well.
