The image shows a close-up of a white wall with a diagonal pattern. The wall appears to be made of concrete or a similar material, with a grayish-white color. The pattern is made up of small squares or rectangles, creating a grid-like design. On the right side of the image, there is a small window with a blue glass pane. The window is framed by a black frame. The image is taken from a low angle, looking up at the wall.
