@streetartutopia Unintentional street art: In Switzerland, the pushbuttons on traffic lights to request green for pedestrians read "FUSSGAENGER DRUECKEN" - In Swiss German, this stands for "Pedestrians, press (here)" - but in standard German, it could also be read as "Push Pedestrians" or, cuter, "Hug Pedestrians".
I think @Fuchskind even made a comic about this once?
