Walker tower was where I lived during my freshman year of college.  It is a terrible looking building. There is little to no natural light throughout most of the building, which combines with the white concrete walls to give off a very cave-like appearance.  The small rooms with single slit windows were also very reminiscent of a prison structure. This was not lessened by the way the entire building is split into discrete sections that require credentials.  It results in you feeling very closed off in the building.
