My current work is a kind of performance without audience, hence only to be photographed. I place my body at the edge of the buildings and take performative self-Portraits. I explore the fear, pleasure, and tension of my body at the edge. From my perspective, the horizontal vision is a kind of fantasy. People perceive, or believe the spectacle of horizontal view is "in front" of them although what actually in front of them are emptiness. At the time, approaching the edge is the moment that people perceive the empty space which is actually in front of them. Hence the fear of heights originated from the moment of perception when vision collapses into the perception of space. I consider we are living in emotional and psychological "edge." Between the reality of emptiness and fantasy far away, we desire the fantasy, but finally our body grabs the reality as my body never falls down. At this point, the stage of my fantasy-the edge- expanded into an emotional and psychological symbol of a vulnerability of humanity.
