For this experiment two persons are required. Both of you sit down facing the mirrors. By slightly changing your position try to adjust the details of your faces so that a new composite image is formed with all the characteristic parts: chin, mouth, nose, eyes, forehead and hair.
How does it work
This installation is built of small mirrors with a width of 3 cm. The mirrors are separated by similar 3 cm gaps. Your faces are partially reflected by the mirrors, and can partially be seen by the person sitting in front of you. If you manage to fit all parts precisely, you will be able to see a new face, which is a result of assembling the parts of two different faces.
Noteworthy is the fact how quickly the brain loses its ability to estimate which parts of the image are true and which are just a reflection. It is only when you focus your eyes on one specific part you are able to start the process of recognition: I recognize a part of my face, so it must be a mirror reflection.
