There’s something that draws out the thought of the French philosopher Henri Lefebvre in the excellent Monument Project. A whole series of time lapse cameras generate a 360 degree image from London’s Monument in the City, London: http://www.themonumentview.net/about.php
With the advent of modernity time has vanished from social space. It is recorded solely on measuring-instruments, on clocks, that are isolated and functionally specialized as this time itself. Lived time loses its form and its social interest — with the exception, that is, of time spent working. Economic space subordinates time to itself; political space expels it as threatening and dangerous (to power). The primacy of the economic and above all of the political implies the supremacy of space over time.
