outside-in, inside-out, or outside/inside?

In the first two assignments I studied various aspects of transparency on vertical planes that form a boundary between the inside and the outside. This boundary can be rather multi-faceted and it can generate different intents/functions/meanings:
-it can allow the outside to manifest its presence to the inside
-it can allow the inside to be revealed to the outside
-it can merge the inside and the outside
-the boundary itself can form an intermediate, ambiguous reality where the play of light, reflections and refractions from the inside and the outside fuse together.
-as a result of the play of light and the treatment of light on this transparent boundary the reality of the outside can be altered as it filters through to the inside.
These qualities promote or inhibit human interactions: does transparency bring us closer or does it keep us apart?
This inside/outside relationship is also important in my thesis research: architecture, and psychology, and an architecture of psychology, deal with inside/outside relationships in many ways.
