This figure shows a close up section of a computer-generated illustration of a post. The middle section of this illustration is colored green while the top and lower quarters are colored red. The top half of the post is leaning to the right hand side, creating a gap, which has formed near the midsection of the post. The upper mouth of the gap appears jagged, and the gap itself is small, running through not even half of the width of the post.
