In the video, a person's finger is seen pointing at a tree bark that has lichen growing on it. The lichen appears to be white and is spread across the surface of the bark. The person's finger moves around, pointing at different areas of the lichen, giving a closer look at the texture and color of the lichen. The background is blurred, but it seems to be a natural setting, possibly a forest or a park. The video does not contain any other objects or actions.
