Computational systems of rules, relationships, and behaviors can extend traditional art and design practices or support new creative workflows. We will explore the creation of computational systems for visual art and design. We will use creative coding platforms and algorithms to create visual works that are flexible, dynamic, and generative. In the process, we will touch on the design philosophy and abstractions of existing creative coding platforms and examine methods to create alternatives. Students learn basic approaches to modify creative programming languages and frameworks or develop new software interfaces for visual expression. Technical production will be complemented by readings on computational art and design theory.
