Polyferro is a reflection on Graffiti. The unreal conjuncture of legal Trainwriting, offered through a feature film shooting, allows the detailed observation of this phenomenon in a kind of laboratory situation. The approach of this film is the wish of finding a quiet and open form. To attend the action in an unagitated and steady way and invite by means of the montage to a different perspective of the subject matter. In doing so the break/ fracture became intuitively a constitutive element of style, on the picture as well as on the sound level, finally shaping the entire structure of the film.
