Windows are a boundary between outer and inner. They constitute a kind of projection screen onto which the outside world is cast for our understanding and visual consumption. That they might frame or serve to limit our visual comprehension allows them to metaphorically denote our necessarily always-incomplete knowledge of the world. In a sense, they symbolise a certain freedom—a view out, a new window on the world. But in another sense, they impose limitation. My windows are not something to look through, but something to look at.
