Conspire, work together, act together, join forces.
arrange (electrical devices or machines) together to work in coordination
As the world becomes a more ambiguous and strange place, I loved the idea that a very small minuscule, microscopic group of people could conspire, cooperate and collude. Together we would have power, and everyone could see it. I mean it is no different to a uniform, and uniforms have been a symbol of solidity, whether for good or for bad. But adding technology to it, we could also be very playful with this.
Have you thought about blinking jackets when people that don't know one another but have common active goals? With a little ML and deep learning you/we could deduce that on the fly when the jackets get close?
