The image shows a close-up of a sandy surface. The sand appears to be light brown in color and has a rough texture. On the right side of the image, there is a black and white ruler with a grid-like pattern on it. The ruler is resting on the sand, and the ruler is slightly tilted to the left. In the center of the sand is a small indentation in the sand. The indentation is in the shape of a letter "I" and is slightly larger than the rest of the text.
