To promote the United Nations’ Sustainable Development Goals (SDGs), painter Leon Löwentraut agreed to translate each goal into a powerful painting. These 17 artworks are now traveling through art galleries worldwide. The challenge was to create an equally powerful digital exhibition that was more than a mere copy of Instagram. On Art4GlobalGoals.com, users not only learn about the SDGs, but also take action on the issues the goals address by using the digital campaign's innovative navigation with digital brushes. To see each of Leon's paintings, visitors must first use these brushes to erase or wipe out the problem identified by the specific goal as way of expressing their support.
