WHEN I WENT OUT IN THE EVENING WITH LAGO, THE DOG WHO WAS ALWAYS WITH ME, I WOULD PHOTOGRAPH THE ASPHALT I WAS WALKING ON WITHOUT ANY REAL REASON. I HAD THE IDEA OF ARRANGING THE PHOTOGRAPHS I HAD TAKEN INTO A NINE-MODULE GRID, LIKE THE SQUARES OF A SUDOKU. I WOULD MOVE THEM HERE AND THERE UNTIL A NEW LANDSCAPE EMERGED FROM THE SUM OF THOSE FRANKLY INSIGNIFICANT PHOTOGRAPHS. THE MODULES THEN GRADUALLY INCREASED IN NUMBER, AND OTHER SUBJECTS WERE ADDED TO THE ASPHALT.
