The ants travel throughout this piece, establishing a subterranean tunnel system, gradually destroying the visible surface, unwittingly dismantling national symbols and indifferently blending allied and enemy territories as they busily transport sand grains from one place to another. It confronts us with a metaphor for the fragility of national identities as the individual, self-contained flags disintegrate before our eyes. Motion and movement, transportation and transformation have proven to be among Yanagi's most effective interventions. Parallel to the declaration of independence of the Republic of Slovenia in 1991, NSK, previously an 'organisation', declared their transformation into a 'State'. For the definition of a proper 'spiritual' territory the concept of NSK emphasizes the notion of time.
Time is understood as a new productive category for the definition of space.
Within this terminology, 'time' is equated with the accumulation of individual 'experiences'. By putting an emphasis on the factor of movement , another productive category for the definition of 'space' is given. It is through movement, i.e. a physical change of location, from one place to another, and through the ensuing intellectual preoccupation with the 'other spiritual territory', that new experiences become possible, leading again to the creation of 'time'. Movement implies temporality, i.e. produces time. This is one of our main concerns, because signs change with time and place.
