The exhibition presents, for the first time in Poland, avant-garde Japanese art from two historical decades, a time of ground-breaking events and transformations that resulted in the emergence of the Japan we know today. It features works by the most important artists of the time, rarely shown outside Japan, and documentation of the avant-garde movements of the time.

The exhibition of works by Hege Lønne, a Norwegian artist with ties to Poland, presents sculptures, installations, video works and documentation of artistic activities from various periods of her career. The exhibition is complemented by unpublished photographs of Warsaw — colour slides from the period of transformation of the 1980s and 1990s — and animated films.

"Simple Rainbow" was created in 1991 for the exhibition entitled "Epitaph and Seven Spaces", curated by Janusz Bogucki and Nina Smolarz. The rainbow stood on Małachowskiego Square until 1993. After 28 years, it will reappear on the square, as a conversation starter on today’s society and world.
