The question of motion in the city and the city in motion is, in fact, a question of the dialectical relation of man and the city (with its architecture). It is a question of being in a constant movement, in a permanent flow, a question of creating an algorithm for writing and reading the rhythm of the city (and its architecture), with its primary functioning principle (in analogy to social life), which is based on mobility and transience. The answer to the problem raised thereby concerns the issue of 'reading' the rhythm of the city and hence the dynamics of social changes using the metaphor of 'figures' moving through the city (starting with the stroll of a 19th century 'flaneur', through a situationist drift, and ending with the walk of a 'flaneuse' in the world of goods), as well as the illustration of peculiar urban and architectural projects, exemplifying setting the architecture and the city into motion. By pointing out the process of 'vivifying' the material world, a parallel is drawn to the motorics of an organism and a human body. The emphasis on 'motioning' the material world in order to be more and more adequate in dealing with human needs. The article proposes a reflection on reading social life within the rhythm of a 'revolutionary' architecture, which rejects its primary, so far, characteristic - stability.
