Good to Sea You Busan begins from the understanding that Busan is not one sea, but 51 different coastlines shaped by distinct ecologies, labor, memory, and material traces. Working across all 51 fishing villages, the project collects seawater and representative marine materials from each site and follows a sustained process of translation. Marine materials become natural pigment; pigment leads to handmade paper; paper becomes the ground for color-sensing and shared performance. The project culminates in a 72-hour live performance, Baekjitjang-do Matdeulmyeon Natda, and a popup exhibition at Space119 in Busan — opening research, transformation, and collective making to the public as a process still in motion.
