Symmetry is all around us but we no longer see it or study it.
Come and start the research.

It is about mirrors and symmetry, playing with the looks and faces of visitors, directly or on their mobile phones. What do you look like in a mirror? Bigger, smaller or the same? Or does it depend on how far away from it you are? How symmetrical is your face? Take a selfie and find out. Is the face you see in the mirror the same as other people see? How can you teach a mirror (or maybe two) right and left, or up and down? A camera, a monitor, a computer: virtual mirrors?
