The image is a black and white sketch of a textured surface. The surface appears to be made up of small, irregularly shaped cells or cells that are arranged in a grid-like pattern. The cells are of different sizes and shapes, with some being larger and some being smaller. The texture of the cells is rough and uneven, with deep grooves and crevices. There are also some small, jagged lines and dots scattered throughout the image, creating a sense of depth and dimension. The overall effect is a complex and intricate design.
