Rivulet is an esolang ('esoteric language') written by Daniel Temkin that uses gylphs to represent programming instructions. While it would not be a practical basis for most programming tasks, it does represent an interesting space between text-encoded programming languages and graphically encoded data visualization. As a language it invites careful thought about 'code layout', as its design offers much more flexibility in visual form than most languages. It encourages us to consider the role that design choices and aesthetics play in helping construct visual schemata. It challenges notions of 'efficiency' in the construction and interpretation of computer code, much like the Atypography movement does with text.
