At the Museum Ariana of Geneva, it is possible to visit FOOD “meditations upon Mother Earth, on agriculture and on feeding” a contemporary art exhibition with works of authors coming from the five continents. Conceived by Adelina von Fürstenberg, this exhibition emphasizes the defence of our Mother Earth, the choice of food, the consequences of the climate change, the poisoning of agricultural products, the gap in food distribution and other themes related with this topic. Among the numerous works, we report the wonderful house “Dumme Gans”, entirely built on Gentilini biscuits. Therefore, they used Novellini for the walls, Osvego for the roof and Brasil for the door. The artist’s intention, Liliana Moro, was to rebuilt the wicked witch’s house of the fable “Hӓnsel and Gretel” of the Brothers Grimm, so nice and sweet-smelling outside but with a lot of tricks inside.
