Noting the inspiration of the Renaissance following the Dark Ages, Danko cited patrons such as the Medici family of Florence, Italy, who funded innovations in art, science and technology from Lorenzo Ghiberti, Filippo Brunelleschi, Leonardo da Vinci and Michelangelo Buonarrati. “Today, we would [say] ‘thinking outside the box’ best
summarizes their kind of creativity,” Danko said. “So, too, does the design and fabrication of this infi nitely curved cast artwork symbolize a new way of thinking.” He said the one-off assembly of castings was unique not only due
to its size and shape but for the ingenuity employed in its creation and design.
A Custom Collaboration “Countless hours of collaboration were spent between
Dr. Ferguson and his team of foundrymen, architects, planners, structural engineers, stone masons, and represen- tatives from the university and the Simons Foundation,” Danko said. Danko Arlington specializes in military and commer- cial aluminum and bronze sand castings. T e company operates a pattern shop, foundry and CNC machine shop in one facility and off ers plating, painting, inserts and light assembly. In operation since 1920, it expanded its operations in 2008, overtaking two adjacent buildings and installing an effi cient system for reclaiming 100% of its spent foundry sand.
