Have you heard about 240 hours long film? 'Modern Times Forever' it's the longest film ever - it lasts 10 days! "A film about what would happen to the Stora Enso building as an architectural and ideological symbol, over the next few thousands of years if only time would affect the building.
The film was shown in Helsinki Market Square on a 40m2 LED screen, so that one could see the original building simultaneously with the building in the film. In the film the building changed all the time. The film lasted ten days, i.e. the work lasted as long as its exhibition period. This continuous exhibition period meant that the film could be watched 24 hours a day for ten days." (superflex)
