How does a crowd move? Do we move differently when alone, from when being amongst a large number of people? What is it that determines the “We”? What is an individual within a group? At the start, there is a stone. With the stone, there is a string. It is rolled up, tangled and we untangle it. We move about, avoiding collision and by negotiating our way we find our place. Eventually, there appears something that surpasses the simple sum of ndividuals. Shall we find the “We” at the end of the string?
