Escher World

Just thinking about my walk yesterday from my office at Midwestern University. My office is on the third floor of building 1. I walked directly over the pedestrian bridge and wound up on the second floor of building 2. I went down to the first floor of building 2 and walked across the Quad straight onto the third floor of building 3. Ground level did not change. This is one of the wonders of working at a venerable institution where the buildings have been potchked together over the years.
