The FOSDEM Lightning Talks are organized by Mattias 'Tias' Guns since 2007. The lightning talks allow projects that do not fit in a developer room to present themselves to the large developer audience at FOSDEM.

Lightning Talks can be described as the 15 minutes of fame for all free or open source projects. During exactly 15 minutes, one person gets to present the project or any aspect of it. All the lightning talks happen in a large room that can host up to 300 people.
