Boards especially placed for self-practicing staring game can be found every now and then.
Some pictures on the board are smiling, some are looking at the somewhere in the space… to make you laugh
These boards can also be used as improving your memory capacities. You can try to remember all the names and faces every time you walk pass by.
Believe or not, the boards are occasionally used to choose people who will spend most of their time chatting the things that are not very important as if they were.
