The video shows a person drawing a 3D box on a white paper using a black pen. The person starts by drawing a horizontal line and then a vertical line, followed by a diagonal line to create a perspective view of the box. The person then draws another box on top of the first one, creating a sense of depth. The person continues to draw several more boxes, each with a perspective view, creating a 3D effect on the paper. The video is shot from a top-down angle, focusing on the person's hand and the drawing.
