The retina is a thin membrane at the back of the eye, the place where the image of the world is first formed. Here, light is never preserved as it is. Countless photoreceptors receive, fragment, transform, and reassemble it̶only then do we experience the act of seeing. The retina is not merely a receptor; it is a device that rewrites the world. 

In Holon Retina, 324 camera lenses cover the wall surface as an artificial retina. Each lens once received light and recorded images, but now they record nothing. Instead, they reflect the figures of visitors and the light at that moment, transforming visual information from the physical realm into the world of imagination. 

Here, the retina is not limited to a part of the body. It is a screen of memory, a boundary between surveillance and observation in modern society, and a perceptual field that connects the individual and the whole. Each of the 324 lenses functions as a holon ̶ an entity that is both whole and part ̶ eventually forming one gigantic retina. This retina visualizes the structure of vision that lies within us, projecting it into the external space. 

Holon Retina is an attempt to materialize the transparent membrane that exists between seeing and being seen - its permeability and invisibility made tangible as a physical substance.
