Kerf Portrait: Driven by the need to tune local flexibility in stiff planar materials to enable the creation of complex three-dimensional shapes and control of wave propagation, a relief cutting (kerfing) method was adopted. Varying the cut density and meander cut patterns allows for precise control of material flexibility, which also displays a gradation of color. A darker color from a higher cut density region is more flexible than a lighter color from a lower cut density region. The artist’s self-portrait is created with varying meander patterns and cut densities on a wood panel using laser cutting. This illustration highlights the interplay of flexibility and color gradation in kerf surfaces. Contributors: Artists: Negar Kalantar and Alireza Bohrani.
