What is this strange place? It might be a temple of some kind, a place of worship? Some people seem to put a lot of effort into climbing those endless stairs, lugging heavy bags along to where they are so eager to get. Others seem to be decending, disillusioned perhaps - shyly glancing at those who do not know, yet, what to expect?
Well, it's really just stairs at Berlin central station, but stretched into infinity this mundane means of transportation becomes a mythical plane on which all sorts different realities become imaginable. The travellers are authentic in their daily routine, yet become actors in a much greater play.
