Realtime projection on the same wall used for Colors but with a new window that has been added by the owner of the building.
The black square (window) in the middle of the wall is a far more stronger element than the pattern of the surface (used in Colors), hence the choice to integrate the square and to ignore the pattern.
Four different rules determine the kind of coloration and transitions of the wall (see bottom page).
