A Subway Named Mobius (1952)

This immediately made me think of the Heinlein story, "And He Built a Crooked House."

Available in .mobi format.

If you happen to be familiar with the MBTA, the opening is a treat.

The Argentinian film Moebius (1996) [1] is based on that story.

I remember this from childhood and tried to find it several times. Nice story. I think of it often when certain software systems I work on become overly complex.
