Thanks, however in that example the player moves indefinitely in a direction and would never encounter any of the objects he had already seen again, thus it is not 'wrapping' back around to the beginning.
Here is an updated diagram: [url:20gs1t7r]http://pub.gamingw.net/39880/wrapping_1.jpg[/url:20gs1t7r]
Imagine you have a cut a vertical strip from a 8.5x11" sheet of paper. You draw your level layout on that strip. Now, take that strip, fold it so that one of the shortest edges touches the opposite edge, and tape it. Now when you go through your level you rotate the ring in your hands, and when you get to one edge of the level you are simply back at the start.
