Us and them is an evolutionary and interactive installation. The sculptures / videos / texts that compose it, interact together via a wifi communication system. Sensors analyze the datas they generate and influence the behavior of the other. Thus the oxygen emitted by the plant makes the wolf run in 3D. The water that is activated by the pump inflates the silicone organs, which themselves modify the projected text in real time ...Nature /culture, technological /organic relationships are built and make the installation an entity of the order of the living.
