The most memorable art exhibitions for me are modern. There's a lot of trash, but one particularly memorable piece is (or was, it's been a while) hanging right on top of the exit door of the Berlinische Galerie. It's just a unpretentious ticker that scrolls a single sentence in red dots: "Do you feel better now?". True, anyone could have done that. But the placement, the simplicity, the style resonated with me in that moment so that I remember that ticker better than Mona Lisa in Paris.
