Interactive installation evolving with the rhythm of the breathing of the spectators. The breaths of the spectators reveal the landscapes of the artwork. Exploring the principle of breathing allows us to evoke the territory which constitutes the atmosphere. We share this territory but we modify it with our various activities. There is an interrelationship between the fact of breathing, of have an action on the environment and to breath this feedback. Also, take time to breathe is a symbolic way for taking again conscience of the natural rhythms, (biological and seasons for example) opposite to the productivity. It's also an invitation to the concentration, the meditation. Breathing : link of this creation, can be interpreted like the continuous exploration of the territory which surrounds our body. We could consider, as Elias Canetti said in connection with the writer Hermann Broch, that each person is a form of atmospheric unit: " the multiplicity of our world also consists, for a good portion, in the multiplicity of our spaces of breathing". We have developed a project as a "respiratory heart". A living work, rythmed by various breaths who linked together the audience. Souffles (Breaths) is an interactive and collective artwork where the breathes of the audience gradually reveal the integrality of several video landscape. These landscape video loops sequences was shooting during times of production in France. At the same time generative and interactive, this video installation evolves progressively with breathings.
