The image is a vintage illustration titled "Fig. 101" depicting three cubes arranged in a row. Each cube is divided into smaller squares, each filled with a different color. The colors used are: Null, White, Yellow, Light yellow, Green, Light green, Blue, Light blue, Red, Pink, Orange, and Ochre. The first cube has a color scheme of Null, White, Yellow, Light yellow, and repeats. The second cube features Blue, Light blue, Green, Light green, and repeats. The third cube mirrors the first, with Null, White, Yellow, Light yellow, and repeats. Below each cube is a number (1, 2, 3) and a caption. The captions read: "Each cube is the beginning of the first tesseract going in the fourth dimension," "Each cube is the beginning of the second tesseract," and "Each cube is the beginning of the third tesseract." The background of the image is a faded yellow, giving it a vintage appearance. The overall style is reminiscent of early 20th-century scientific illustrations.
