A stack of colorful blocks is shown in the image. The blocks are rectangular in shape and have a series of small, circular protrusions on their top surfaces. They are arranged in a staggered formation, with some blocks placed on top of others at an angle. The colors of the blocks include pink, white, yellow, green, and gray. The blocks are arranged in a way that creates a visually appealing pattern, with the different colors and shapes creating a sense of depth and texture.
