Hint: to get more content to look at, run the Physics sample application (Bin/Data/Scripts/11_Physics.as), and press F5. This saves a scene file called Physics.xml into the Data/Scenes subdirectory, which can be loaded in the editor. Scenes utilized by the NinjaSnowWar and SceneAndUILoad examples also exist in the Data/Scenes subdirectory, and the NinjaSnowWar object "prefabs" are in the Data/Objects subdirectory.
