Whether as participants, organizers, or through the activated Asuciación, a wide range of interactions, explorations, and experiences can function as collaborations. In some cases, the source of the work is someone else's idea, while in other cases people are invited to explore with PBO or the Asuciación. Some interactions begin with curiosity about certain phenomena, facts or proposals. The common denominator of all these encounters is sharing, learning and, ideally, having fun together.
