After working on more or less large-scale spatial organisations, ranging from a courtyard to the Seine Valley between Paris and Le Havre, Sanejouand decided to take the plunge and organise the whole planet Earth, or at least one of its hemispheres. To do this, he started with one of his previous organisations of space (36 pictures or drawings of Organisations of space form a frame around each planisphere), chose a hemisphere, the North or the South, and from there arose associations of ideas that led him to paint Australia red or the waters brown, to highlight certain places. He visualises specific ideas in this way. But he doesn't say why, because he's convinced that if he uses the same method again 15 days or 6 months later he won't have the same associations of ideas. And what interests Sanejouand here is not imposing his associations of ideas on others by explaining them, but on the contrary, suggesting other associations of mind that each person can make freely. It's a kind of free play.
