French-Canadian Photographer Benoit Paillé and his family have been going to various Rainbow Gatherings for 7 years, and he has been documenting them for 3. The photo's that he has captured are fascinating and a true eye opener to what amazing things people are doing. Below is a quote taken from this project, it should help explain exactly what the Rainbow Family represent, and why they do what they do.
The largest non-organization of non-members in the world. We have no leaders, and no organization. To be honest, the Rainbow Family means different things to different people. I think it's safe to say we're into intentional community building, non-violence, and alternative lifestyles. We also believe that Peace and Love are a great thing, and there isn't enough of that in this world.
