In 2009 LAFKON developed a Free Software framework for the process-based generation of posters for the make art festival.
Processing, an open source "programming language and integrated development environment (IDE) built for the electronic arts and visual design communities" meets software dinosaurs like Donald Knuth's typesetting program TeX and GNU's Unix shell bash. This means WYSISWM instead of WYSIWYG, control code generated with the bash, layout done with LaTeX, decorative graphics rendered with Processing and some bash wickedness.
Processing sketches are mostly based on GPL licensed code from openprocessing.org.
