 * &lt;p&gt; A playyard to demonstrate NavigationInfo operation. This world illustrates the use of a NavigationInfo node to set the size of the users avatar (width, height, stepsize). The playyard contains several obstacles, some of which the users can get past and others they cannot, all because of the size of the avatar. &lt;/p&gt;
