To Breathe (2022) is a site-specific artwork consisting of diffraction grating film that allows natural light to constantly transform in tune with the flow of time, changes in weather and movements of the sun throughout the four seasons. The reflective film yields rainbow spectrums and generates unique compositions according to viewers’ movements, resonating with Kimsooja’s ongoing investigation of painting and two-dimensionality. As light passes through the diffraction grating film, which is covered in nano-sized scratches that act as a prism, the interior space is filled with iridescent rays. Such refraction and breathing of the light awaken the audience’s sentiments and thoughts, allowing for both a metaphorical and embodied experience of the artist’s nonmaterial practice of “non-doing, non-making” with light painting. Transposed into light in To Breathe, Kimsooja’s artistic language transcends notions of materiality and delivers the breath of nature unto all beings within its embrace, from the moment the very first life took its first breath until the present, in the same way that light has always unconditionally sheltered and touched countless beings.
