Our friends of the Computerspielemuseum [1] in Berlin (Museum for Computer Games) participated in the "Lange Nacht der Museen" (Long night of the Museums) two weeks ago. During this event all museums in Berlin are open until very late and people can just buy one ticket to visit all of them.
They also created a mission for Tidy City around Karl-Marx-Allee and handed out smartphones to interested visitors who could then try to solve the mysterious mess that waited for them. Maybe we will soon see some more missions in Berlin?
Here are some impressions from the event:
