When a person moves, a force is applied in that direction. As a result a flow occurs. When a fast flow occurs a rotation phenomenon is produced due to the difference in the flow velocity around it, creating a vortex.
The faster the person moves, the stronger the force is applied in that direction. If a person is not moving or there are no more people, no flow will occur and nothing will be present in the space.
Works are born and continue to transform under the influence of people’s movement.
