The exhibition “Roads Not Taken” at Deutsches Historisches Museum presents an unusual look at the past. Conceived by historian Dan Diner, it explores 14 tipping points in German history that could easily have taken a different turn. To spatially implement the abstract mind game of “Roads not Taken”, scenographers chezweitz created a congenial exhibition design: Using the architectural tools of perspective and trompe l’oeuil, they designed powerful “possibility spaces” that distort or dissolve—depending on the viewpoint: the mind game turns into a visual game.
