Residents of an apartment building notice subtle changes in a hallway painting — trees shift, water rises, colors change, and eventually a mysterious figure appears and slowly moves closer over time. Photos confirm the painting evolves day by day, independent of reality outside. When the figure finally reaches the foreground, reflections inside the painting begin to mirror the hallway itself. The residents stop documenting it, but unsettling sounds suggest whatever exists inside the painting may now be approaching the real world.
