Ghost people

In pedestrian crowds, people seem to behave independently: everyone has his own motivation, destination, and walking speed. However, people are also under the influence of others: they avoid, follow, and sometimes push their neighbors. In dense crowds, these influences often give rise to collective behaviors, such as dangerous stampedes.
This photography illustrates the paradox of crowds: people seemingly ignoring each other, but contributing to the emergence of a large-scale cognitive system.
