As homage to the American desert southwest home of Arizona State University, a sweeping, 40’ long by 10’ high sandstone feature wall greets visitors in the building lobby.The computationally generated surface of the wall topography are not ‘hidden’ but rather are celebrated in a triangulated pattern allowed to read through in the final product. The triangulation edges are a result of the stone tooling, a diamond-bit rope on two Computer Numeric Controlled pulleys are able to carve a ruled surface through the stone slabs. The crisp edges of the CNC fabrication were ‘swept’ by laying up the entire wall and hand-sandblast sculpting the surface to bring out the striation and create uniformity to the final form. Finally, dramatic, grazed-lighting highlights the CNC-sculpted stone, capturing the relief and detail of the surface. The result is a hybrid of digitally developed modeling and hand-finished circumstance that bridges the line between natural and computer generated form.
