Original Description:
The Gazebo Demo shows of some reflection and mirror effects made possible with the undoc'd feature no_depth flags. Although the gazebo is reflected in the water, its the table inside that really shows off. It reflects not only the Gazebo, but the skybox, and bouncing balls, with the addition of a swirling texture.
Note: On some cards the swirly texture on the table hides the reflection effect for some unknown reason. If you don't see any reflection on the table, simply press 4 (or is it 5?) to toggle the swirly texture on/off.
