The video shows a close-up of a blue surface with a bright light shining on it. The light appears to be a UV light, as it glows brightly and casts a blue hue on the surface. The light is moving in a circular motion, creating a pattern of light and shadow on the surface. The surface itself is not clearly visible, but it appears to be a solid, smooth material. The UV light is the main focus of the video, and its movement is the only action taking place.
