Developed as 2017 ECO ART TRIP — 엄마야 누나야 강변살자, the project took place along the lower section of Daecheoncheon Stream, an urban ecological waterway in Buk-gu, Busan. It approached the stream as a lived site of environmental reflection and public encounter, focusing on plastic waste and biodiversity through a site-specific collaboration that wove together environment, local community, technology, and art. At the center of the project was an eco art journey structured around Bluetooth beacon and location-based mobile content. Participants encountered upcycled installations along the stream, accessed ecological stories and field data through their smartphones, and moved through the site as active participants rather than passive viewers. The project unfolded across months of community process: a BioBlitz ecological survey conducted with local naturalists in May, a Green School upcycling workshop with youth in June, and an interactive ECO ART Boat — built from plastic PET bottles and equipped with solar panel, LED, speaker, and IoT connectivity — that responded in real time to audience presence. Artworks in video, sound, painting, and webtoon, derived from the BioBlitz, were installed as beacon-activated content throughout the site. Living Along Daecheoncheon expanded the ECO ART TRIP methodology into a more community-rooted and technologically mediated public practice, continuing the project's sustained inquiry into ecological futures through participatory art.
