The dotted circles are a metaphor for an ideal society, with porous and intersecting perimeters of groups of people.
Regardless of the reasons that make groups seem open or impenetrable at any given moment, groups are made of people who each want to live a full life. That’s why they join and create groups with others! So despite expressed and arcane rules of inclusion and exclusion, intersecting circles is still a valid representation of society.
Welcoming and serendipitous opportunities help keep society open, functional, and optimistic.
Finally, the Easter colour scheme is in homage to Prince, and our perpetual project of dying and being reborn to our multifaceted, divine nature.
