To Eternity is an interactive media art installation commemorating the Gwangju Democratization Movement of May 18, 1980. Archival photographs taken during the 1980 uprising are algorithmically mosaicked in real time over the viewer’s image. As participants adopt a gesture of offering—such as placing flowers—the system recognizes the movement and completes the visual composition. The result is a digital altar that transforms silent remembrance into shared visual memory, allowing audiences to engage in a contemporary ritual of tribute through interaction and presence.
