This wall is a poem of time, blended in the gray tones. The light gray is like morning mist spreading over the brick surface, while the dark gray is like dusk seeping into the brick gaps. The two tones alternate like breathing, weaving ripples of light and darkness within the vertical order. 

It is not a rigid alignment, but rather a staggered arrangement with a breathing rhythm: The edges of the bricks in the upper row gently rest on the gaps of the bricks below, like the joints of keys touching each other on a piano. It not only supports the heavy and raw texture of the wall but also lets the whispers of the wind seep through the gaps.
