The Convexity problem, an exercise in organic form. Unlike some of the other 3-Dimensional design problems, which are compositions of elements, this one is a single form usually with no negative space involved. It is more about the subtle gesture of rounded volumes and slowly developing the surface over the course of the semester. This piece is over 20 years old, from when I was an industrial design student at Pratt Institute. Taking the first 3D class taught by Linda Celentano after the great Bill Fogler left us. I was extremely lucky to have Bill Fogler’s last class and Linda Celentano’s first class.
