Moebius Ring

An example would be a group of 9 square rooms, 3x3 formation, where one might cross into a room through an initial entrance, take four "right turns", and discover that the fourth turn, which should lead them back to their initial starting room, is actually a different room than their starting room. The identical nature of the rooms keeps the "user" from noticing any startling telltale signs that they're retraversing previous rooms, and give the alarming sensation that the interconnected rooms go on forever in every direction. An instance would include looking through a single doorway (usually placed in the middle of each of the four walls) which would produce a never-ending distance, which would be accomplished by never showing the first room that the user is standing in, but a succession of the other rooms through specific doors (eg. so they don't see themselves and their back looking through the door).

Moebius Ring in Pop Culture

A Moebius Ring appeared in episode 66 of the Bleach (manga) anime, where they used a red string tied to a starting room to realize that they were retraversing old rooms.Fact|date=December 2007

The 'mazes' in Cube film series could be considered as a 3-dimensional version of the Moebius Ring.
