Guerrilla Innovation tells us about a fabulous public space concept, Permanent Breakfast that kicked off as an experiment in the 90s and has since swept through the world. It's a 'continuous social experiment that can be executed by anyone, anywhere. The experiment was conceived in 1996 by the Austrian artist Friedemann Derschmid and the basic idea is to bring people together to have breakfast in public spaces that are not necessarily obvious picnic spots, thereby modifying the way we think of these spaces as well as stimulating social interaction in them.

Naturally, anyone can do this without it being an art project, so to be an authentic Permanent Breakfast event, there are some rules that participants must follow: The organizer must invite at least four people under the condition that each one of them subsequently invites four other people for a new breakfast to be held somewhere else. And so on.'
