Berlin is the place where people always communicate with the environment visually, adding new living meanings to a city. Monochromatic Andrei Sakharov, inventor of nuclear bomb, dissident and human rights activist, was depicted on the Berlin Wall by Dmitry Vrubel and Viktoria Timofeeva. A buddhist monk in his shining robes is a ‘calm mind’ meeting Sakharov’s ‘troubled mind’.
