The Japanese artist Tadashi Kawamata creates nests of civil disobedience with his Berlin Tree Huts that spread from the Haus to the trees in the park, while interrogating the architecture of modernity. His "social sculptures" were exhibited at both Documenta 8 and 9, the Venice Biennale and Shanghai. The Gallery-to-go offers a platform for creatively thinking about the exhibitions.
