Michael Pryor was invited to be a guest critic for Jose Luis García del Castillo’s Harvard GSD course “Introduction to Computational Design” alongside Madeline Gannon, Aurgho Jyoti, Nono Martínez Alonso, Scott Mitchell, Mariana Popescu, Jenny Sabin, Robert Stuart-Smith, Tara Tan, and Maria Yablonina. The course is unique in that there is no set brief, but rather students are challenged to tackle and solve problems of their own interests and develop them alongside knowledgeable tutors. The only rules are that these problems must be explored via computational methods and algorithmic thinking. Common themes explored were virtual reality, gamification, social platforms, optimization, simulations, and sustainability.
