Walter Netsch, former principal at Skidmore, Owings, and Merrill, is well known for his work with field theory, a method of design based on fields of rotated grids. In the 1960s Netsch applied this technique to a number of projects, including the campus of the University of Illinois at Chicago. His contribution to Late Entries playfully extrudes the grid into a tower, a pattern that he described as a butterfly in a field of flowers.
