The International Free Software Forum - FISL - took place annually from 2000 to 2018 in Porto Alegre, Brazil. FISL is considered one of the world's most significant open-source events, providing integrated technical, political, and social discussions about free software. In July 2012, the event hosted 7,709 participants from 23 countries. At the invitation of the event's organization, we gave a lecture. We also created artwork based on the event's logo, which was featured on posters throughout the exhibition area, and stickers were distributed to participants (along with stickers from other exhibitions).
