The third layer is the physical space of the installation, which transforms based on the viewer's presence. A camera embedded in the installation detects when a viewer approaches, triggering a shift in the space from 3D to 2D, encouraging viewers to take time exploring the space and witnessing its changing behavior and imagery. This layer invites participants to step into a transitional zone, bridging personal introspection, digital interaction, and physical reality. Through this immersive experience, "Liminal Space" evokes a sense of disorientation, nostalgia, and contemplation, encouraging viewers to reflect on the transient nature of the spaces we inhabit, both online and offline.
