Boxes' model. The purpose is to assemble boxes in the ascension. These plasters build isolation and darkness, both are the feelings of Chloé in L'écume des jours. Here is the first test of the objective by putting smaller box on a bigger one. It would be now a narrow corridor without light in the dark basement of L'Aula des Cèdres in Lausanne.

Ladder's test. Experimentation of a second way to climb from one slab to another.

Second cardboard's test : light's gradation from the bottom to the top (verticals) with the shadow on the column. 

First cardboard's test in context with red string on the Plus column. Abstract stairs hanging on the emptiness : system of "port-à-faux". 

Script's passage of L'écume des jours written by the french producer Michel Gondry ("love" triangle). It's a script that helps us to develop an idea, and how to feel and occupy the space for Planes. The column's universe has to create an atmosphere (space) that can be played in real life by actors of the scenario.
