The Historisches Museum Baden is currently running a special exhibition entitled Kosmos Kino: Zwischen Traum, Sitte und Kommerz.  

"Turning the museum into a cinema, the film is the exhibit playing not on the screen, but in the heads of visitors..."

The exhibition opened on 3 September 2017 and runs until 25 February 2018. You can listen to a review on this German-language podcast.
