Since thinking about how to create the atmosphere and presence of this being in our set, I have recently found a new production of Metamorphasis which toured in 09' which does this well. the set was built one on top of the other. Seeing the character constantly learing ontop of the other charaters creates this very unsettling atmosphere.

In a group meeting we wanted to create two different atmospheres in each room we make. one being tidy but knowing his presence is there, then his room which he has created into a nest like room.
