윤슬 (Ever-Changing) is an audiovisual installation, based on an original musical composition of the same name for an 8-key marimba and two of processed field recordings. The installation features clips of streaming water, shimmering over ripples—reflecting the meaning of the title “윤슬”—within a computational environment. It intermittently displays unique graphic notation for the 8-key marimba, fragments of original poems about water circulation, and visual elements reminiscent of video editing software. The juxtaposition of the uninterrupted flow of water against the structured, computer-generated visuals creates a compelling contrast.
