First a short neutral scene is played with (at least) three players. Afterwards the audience is asked from the perspective of which player they want to see the scene again. For this player the audience indicates what the player thinks of the other (two) players. Then the scene is repeated from the perspective of the chosen player. This is then repeated two times, from the perspective of the other two players.
The emotions need to be expressed as big as possible. Exaggerating is an art. Besides, the scene can change a bit because of it. If you play from someone’s perspective the other players get an assignment. The player from whose perspective you play stays neutral, the other players play the task out. In principle the scene is repeated three times but that is not necessary.
Variation: In the second version of the perspective the audience isn’t asked what the players think of each other but this is filled in by the players themselves. This version is more subtle than the first perspective. What the players think of each other is derived from the first scene. For the audience this is a bit harder to follow, so only play with a patient audience.
