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.
Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as:
HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS
only to find a reference to another leaf: Please see
HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS
and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.
