The video shows a person's hand placing yellow and blue plastic blocks on a blue base. The person is building a structure with the blocks, and the camera moves around to show the progress of the construction. The blocks are rectangular in shape, and the person is carefully placing them to create a pattern. The blue base is flat and serves as the foundation for the structure. The yellow blocks are placed on top of the blue base, creating a contrast between the two colors. The person's hand is visible as they manipulate the blocks, and the camera angle changes to show different perspectives of the construction.
