A vertically oriented image depicts a section of an indoor wall in Sofia, Bulgaria, specifically at the 128 SU Hristo Botev school. The wall is predominantly covered by a green, textured moss and plant installation. Central to the upper half of the display are the numbers "128," formed from a vibrant, light green, textured moss. The surrounding vertical garden incorporates various shades of green moss, including rounded clumps and flatter sections, interspersed with dark green fern fronds and smaller clusters of leafy foliage. Some foliage exhibits reddish-brown or dried characteristics. Below the moss numbers, a thin, gold-colored rectangular frame is embedded within the green wall. Inside this frame, towards the bottom left, a small, red rectangular plaque with a white stylized emblem, resembling a building with a flag, is visible. The moss installation terminates above a plain yellow wall surface, which extends downwards to an indiscernible floor line. No individuals or active subjects are present in the scene.
