The starting point for Six’s work are very individual experiences and recollections of her childhood. She considers the imagined, memorized space to be a heterotopy. "Perhaps a heterotopy can be compared to the moment you see yourself in a mirror. You see yourself in a different space but you are aware of the fact that you are not really there. Sometimes, when I see myself in a mirror I can hardly understand that the person I see is myself." Unmasking this sort of space causes a kind of evaporation of it into tangible reality.
An important element in Six's installations is the use of primary shapes as building element. She casts her memory into prototypical shapes and basic constructions. In this way, a private perspective is linked to a general foundation upon which our consciousness is built. What makes the foundation of memory? It is this memory which is centrally present in A Backyard Journey, and in an attempt to make the past comprehensible a spatial installation comes into being.
