With Russia's war of aggression and invasion of the sovereign neighboring state Ukraine since 24.02.2022, the power of the art is not extinguished. 'l'énigme du jour' (Riddle of the Day) is created in March 2022 in Kyiv during the encirclement, siege and bombardment of the city by the Russian troops. It is a dialogue between the Ukrainian artists Dana Kavelina and Nikita Kadan.
