English: LENNA is a procedural generative system that automates the graphic design process, producing posters that follow the principles of the International Typographic Style. The system uses a custom-written algorithm, a plot printer, and an LED monitor to display the real-time calculation process. It questions the boundary of computability by fabricating a surrealist paradox - while the outcome looks organic and creative, the process is fully automated and governed by predefined mathematical principles beyond human perception.
