The video shows a close-up of a person's hand holding a white 3D printed device. The device has a small screen on the front and two black buttons on the side. The person's thumb is pressing one of the buttons, causing the screen to display a black object. The object appears to be a remote control with a grid of buttons. The person's hand is steady, and the button presses are deliberate. The background is blurred, but it appears to be a white surface.
