Christmas decoration of the balconies and the psychism of the neighbor, is a study of the arrangement of decorative items of urban balconies during Christmas period.Throughout the city, balcony "rails" are created by intricate compositions of Christmas lights that, depending on their shapes and colors, form and communicate messages reflecting the cultural and social situations of their owners, readily interacting with the city and the passer-by.The ornamental arrangement suggests a phenomenological approach of pluralistic improvised compositions, which could possibly be considered as "informal artistic installations" made by "the adorner neighbor".The elements of the adorner, work as a form of "otherness" that comes to define along with us the space, and create traces of a cosmogeographic psychism structured through our "cultural baggage"-meaning individual loads that each adorner bears in relation to his/her sociocultural background-. Additional factor referred to "cultural loads " is the individual "horizon of expectation" that shapes our perception every time we come in contact with a work of art. Plotinus: Trace is the form of the amorphous.
