The interactive image installation brings spectators into an unexpected encounter with the witness of their disappearance in digital media. In this era, a person’s image spread on social network could be considered the equivalent of his being in reality. How will one feel if faced with his failure to be detected and recognized by digital media? Would it trigger solitude and sentiment in one’s heart, even if the estrangement and alienation only takes place in a virtual environment? The discussion is then extended to ontology given that in order to witness one’s corrosion one has to stare at himself and endure his progressive disappearance. The installation might further symbolize the caprice of system surveillance currently in the post-information age, or possibly in cyberpunk future.
