One day workshop at Fig Festival (Liège, BE). To get participants familiar with both collaborative coding and web to print, we decided to build a poster tool, Live CSS (name still being questionned). It allowed 44 users to write all at the same time on the same CSS stylesheet and to save stages of the poster. It’s based on Etherpad and Grav Cms, to which we added a small plugin.
