 * &lt;p&gt; A dungeon door that slides open when visible, and slides closed when not visible. When you are look away from the door it goes shut, then it reopens when you look back. Page up/down between the first two viewpoints to observe this behavior. Arrow keys also help you peek left/right. Interesting side effect: users can't back up through the closed door. &lt;/p&gt;
