The video shows a person's hand holding a black marker and drawing on a white surface. The person starts by drawing a curved line, then adds a triangle on top of it, and continues to draw more lines and shapes, creating a 3D drawing of a house. The drawing is simple and basic, with no colors or shading. The person's hand is steady, and the marker moves smoothly on the surface. The video is shot from a top-down perspective, focusing on the drawing and the person's hand.
