Extended Playtime is a project of geneva art group Collectif Fact. It's a good reflection of the lack of 'spatial continuity' in cinema (the fact that scenes are shot and shown independently). In this project, they extended the 'Playtime' movie (by Jacques Tati) through an interesting experimentation: they put in a 3D space all the parts shot in the waiting room of Playtime. The point is to show a often neglected space: a place visible on all the scenes.
