<p>Error 404 is the message received by internet users when trying to access a broken website or a corrupted page link. The phrase Error 404 acquires here a rather metaphorical sense, 'error' being not only the sign of a system failure, but, as the subtitle indicates, the mark of possible Territories of Absence. The latter indicates the absence of a functional and communication space, of information itself, whether they are part of the real world or the virtual realm.</p> <p>However, this absence is not a lack but rather a temporary suspension of presence. The artworks included in this research-exhibition project deal with the idea of error, blur, glitch and absence equally in a concrete way (i.e. technical, formal, visual) and in a conceptual sense, pointing to the (im)possibility of representation, communication and bodily interaction in situ. The reference to technological vocabulary is no coincidence as all the works selected are based in a way or another on media technology such as interactive systems, video installations, one channel video, digital print etc.</p>
