In the video, a man is seen standing in front of a blackboard. He is holding a marker and drawing a green cube on the blackboard. He then proceeds to draw lines on the cube, connecting the corners and sides. The man continues to draw, adding more lines to the cube, making it appear more complex. Throughout the video, the man speaks to the camera, explaining his process of drawing the cube. The video ends with the man finishing his drawing and looking at the camera.
