In addition to managing the flow of people in the spaces of the museum in order to maximize freedom of movement and choice, Irwin also modified the industrial window grids to create perceptual ambiguity, placing transparent glass in the inner four panes while using frosted glass for the outer panes. With this, Irwin solved the problem of either having the windows become a wall of glaring light, if all transparent glass was used, or having them become a claustrophobic muffling of space, if all frosted glass was used. Irwin's windows catch the eye in a back and forth oscillation between distant and proximal focus.
It is unusual to find such mismatched elements on a single facade as this fine stonework coexisting with these stained and rotting shutters, on a house in the fortified town of Feltre, in the northern Italian province of Belluno.
Where considerable labour lies behind the cutting and fitting of the stone, the timber planks have been left in their raw state, with no paint or carved decoration. Even the iron hinges are of the plainest variety.
Take the use of enormous plate windows...they deprive our buildings of intimacy, the effect of shadow and atmosphere. Architects all over the world have been mistaken in the proportions which they have assigned to large plate windows or spaces opening to the outside. We have lost our sense of intimate life, and have become forced to live public lives, essentially away from home.
Picture a blind man probing his way with a cane. While he is alert to the feelings in the hand holding the cane, the crucial distinction may be defined by saying that these feelings are not watched in themselves, but that he watches something else by way of them, that is, by keeping aware of them. He has a subsidiary awareness of the feelings in his hand, feelings which are merged into a focal awareness at the end of the cane, constituting two kinds of awareness that are mutually exclusive — "from awareness" and "focal awareness".
There is here a particularly interesting phenomenal transformation. The sensations of the cane on his hand (the surface of the cane as it touches the palm of his hand, etc.) are lost. Instead, he feels the end of the cane as it touches an object...If our blind man shifts his attention from the tip of his cane to his hand, the meaning on the end of the cane disappears.
