WhO

Designed by artist Soji Matsunobu. The work is a conceptual artwork in which black/shadow is reinterpreted as a physical drawing line. When approached, it is a hand-drawn line; when separated, it is a complex pattern like moiré; and as an action, it represents "fill" or "cancel = nothingness.
Just as there are infinite gradations (grayscale) between black and white, different designs can be created infinitely from the slightest difference in brushstrokes.
Carefully designed drawings become wallpaper that can neither be "ground" nor "figure," creating a new perceptual experience in space.
