The video shows a man kneeling on the floor and building a structure with large plastic blocks. The man is wearing a green shirt and a black cap. The blocks are in different colors, including red, blue, yellow, and green. The man is carefully placing each block on top of the other to create a rectangular shape. The structure is quite large and takes up a significant portion of the floor space. The man appears to be focused on his task, and there is no one else in the room.
