We chose the niche as our exhibition space because it allowed us to maintain a necessary distance from other sound-based projects. Additionally, this setup ensured that the work could only be viewed from the front, preventing visitors from accidentally bumping into it and disturbing any components. | We chose the niche as our exhibition space because it allowed us to maintain a necessary distance from other sound-based projects.
