The form of Digital arts is unpredictable; an installation of one-channel or multi-channel projection(s) via monitors (of different types of screen) or projectors (of different types of material) and a plethora of published or DIY software programs and machinery, such as, adaptable across tablets, PCs, cameras, microphones & speakers, transducers, cellphones, the Internet, etc. Some artists have made digital artworks to cast their personal gaze upon existential matters focusing on emotional & behavioral patterns, while others are challenging the dominant perceptions of socio-economic-political reality. They both use digital means to dispel preconceptions of what is appropriate or enjoyable by eschewing the standard blueprints of routine narration, or by providing deeply private and taboo subjects as artworks, or by shaking up our thoughts about how life may have been felt and lived. The talk starts from the fact of the sustainable nature of these works to examine through a series of examples the following thought: How life in urban nets would be felt and lived if public spaces were performative, by works of digital art, new media art, multimedia art, interactive art, computer art, AI art? If on our routes we had the experience of being immersed in a virtual reality environment, or in installations of 3D visualizations of complex information structures?
