Similar arrangement to 1, except that the entry and exit are shifted relative to each other. The left side of the entry is in the mid position of the wall, while the right side of the exit is in the mid position. Note that the average path of travel will tend to skew towards the right, from the entry point to about the center of the room.

The tendency for the skewing on the right hand side is a result of the individuals simple momentum as a result of walking. Although in later diagrams I may explore how conditions leading to the entry may effect momentum, right now, for the current series of diagrams I am assuming the area leading to the entry of the room to be wide open and featureless.
