PeepingWho is an immersive interactive installation that challenges viewers to reevaluate voyeurism, privacy, and personal boundaries. Through several mysterious peepholes on an ordinary door, participants find themselves confronted with livestream scenes of their own act of peeping. This self-referential peeping observation intensifies the feelings of vulnerability and prompts introspection, urging participants to consider the intricate power dynamic of their behavior: Who is peeping Who?
