Paulina Włostowska had the opportunity to become acquainted with the works of her late neighbour, the local artist Czesław Gendek — a painter who created works in various techniques and who was involved with applied graphics, exhibitions and advertising. The Gendek family studio housed both the unfinished works of the artist and the tools of his everyday craft. Włostowska never met the painter personally, so she only came across an orphaned space and objects that had lost their meaning and function.

An experimenter in the field of cinematographic techniques and a film education pioneer, originator and founder of the Film Drawing Studio at the Academy of Fine Arts in Kraków (1957–1972) — the first such institution in the world offering education in animation at a higher artistic school.

"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.

The exhibition consists of seven films by outstanding and renowned artists; some of them are presented for the first time. They show in different ways the condition of people, the Earth, what we are losing and what we desire, the effects of the different forms of alienation that we experience globally today. They make us aware of the causes of alienation, the mechanisms of destructive human behaviour, recalling historical and contemporary events that affect the state of today’s world.

The exhibition project was inspired by the historical exhibition of the works of the German graphic artist, sculptor and painter Käthe Kollwitz, which took place in the Zachęta Central Bureau of Art Exhibitions (CBWA) in 1951. The development of documentation and analysis of the exhibition reception was possible thanks to a research project conducted in recent years at the Zachęta gallery, in which exhibitions, rather than individual works, were the subject of research.
