As a starting point for my reflections based on the film-process BLANK I establish a brief link between one of the possible conceptions of art and the path by which the artistic idea – already a phenomenon in the creator's mind – becomes an artwork characterized by its constant mutation. This relationship leads me directly to questioning the human need to produce and store signs with the deliberate intention of perpetuating in time - through the use of symbolic languages - ephemeral situations, data that will later form a collective memory, a cultural device.
