This is the making-of film of the pop-up exhibition celebrating the birthday of LE SSERAFIM's Sakura, held at 'Scène', a complex cultural space in Seongsu-dong. Breaking away from conventional, simple photo-display exhibitions, we installed the 'Selviewer Signage' in the center of the store—featuring transparent films applied to specially manufactured, atypical polycarbonate panels to enable dual-sided viewing. Utilizing projection mapping, we produced interactive content where Sakura's fan art and supportive messages from fans appear in real time. On the large wall, we projected the artist's performance videos and sincere text typography in a wide format to maximize the spatial immersion. From 3D hardware design to beam projector installation and interactive software development, SUPERSELL executed the project as a turn-key solution, delivering a high-end reference that presents a new audiovisual paradigm for entertainment pop-up stores.
