Poster for Kulturnatten (night of culture). Kulturnatten is a cultural event taking place every year in Copenhagen. It is one night only, where 250 museum, theatres, libraries, churches, parks etc. are inviting people to come and have a look behind the scenes. The writing on the poster appears from the negative space between the buildings of Copenhagen, which is where the event takes place. The poster works as an optical illusion, and can be seen in two different ways. Like culture, not everyone sees the same thing. Some see the blue/grey color being the rooftops of the buildings and the dark blue being the roads, some see it the other way around, with the dark blue popping out as the rooftops.
