In the 1980s, Serra found himself in the center of a public controversy over his piece titled Tilted Arc. While it was the government that approached him to create the work for downtown Manhattan’s Federal Plaza, the unveiling of the piece in 1981 was met with sharp criticism. The monumental sculpture was said to disrupt rush hour and the pedestrians who had to cut through the plaza daily. To the dismay of art lovers, the 120-foot-long, 12-foot-tall Tilted Arc was ultimately disassembled in 1989.
An important feature of their strategy is parallel working - keeping design activity going at many levels simultaneously. The best cognitive aid for supporting and maintaining parallel design thinking is drawing. Drawing with the conventional tools of paper and pencil gives the flexibility to shift levels of detail instantaneously; allows partial, different views at different levels of detail to be developed side by side, or above and below and overlapping; keeps records of previous views, ideas and notes that can be accessed relatively quickly and inserted into the current frame of reference; permits and encourages the simultaneous, non-hierarchical participation of co-workers, using a common representation.
The drawing of partial solutions or representations also aids the designer’s thinking processes, and provides some ‘talk-back’. As well as drawing, innovative designers frequently like to undertake practical work related to the design solution, such as building models or mock-ups, or participating in construction.
