Make two into one

Floor 1 | Mindscapes
Three visitors sit at a table, two of them opposite each other, the third at right angles to them. The two people sitting opposite each other look through glasses. The third looks into two mirrors that are arranged at right angles to each other. Only the person sitting on the right is seen through the right eye, and the person sitting on the left is seen through the left eye. Because the brain simultaneously receives different information through the two eyes, the two faces are fused together.
