Considered as one of the pioneers of net.art, since the early 1990s Vuk Ćosić has been carrying out multidisciplinary and innovative research on the language of art conveyed by the Internet and its potential effects on contemporary society and life. Going beyond the simplistic assumption according to which the web represents a virtually endless space of freedom of expression, in his works and in theoretical reflections the artist develops a generative and critical idea aimed at emphasizing the relevance of artistic action carried out on the web in the broader context of relationships among individuals. The complexity of contemporary life, in all its facets, is thus at the center of a hybrid investigation that uses, misuses and abuses the web, its quirks and its languages, its universally accessible nature and its immediate circulation, as a point of departure to arrive somewhere else, in a space that is both real and virtual and layered with meanings. The seamless combination of everyday and artistic actions pervades Ćosić’s practice, at once rooted in the present, projected towards the future and connected with the past. If, as the artist paradoxically states, “the art of the past was only a substitute for the internet,” this same legacy can become the subject and object of new actions born of and spread around the web. This endless game of cross-references is the basis of the video Unboxing Duchamp’s Boîte (2021), in which the artist is caught in the act of opening the packaging of an edition of the iconic Boîte-en-valise by Marcel Duchamp. Ćosić appears in the symbolic moment of his artistic epiphany, which took place during the years he lived in the city of Belgrade. The images are supported by the voiceover of the artist himself who, alternating between his own language and English, creates a short circuit of meaning, which tells us of identity and otherness, and at the same time of an universal language generated with the development of net.art.
