FORUM BOX: Growth
What is growth?
An internal experience, a creative process, a form of material and spatial development. Wondering at life and humanity, the continuous cycle of living beings.
A work of art is always both a final result and part of ongoing change.
The artists of the second exhibition in the 2026 series are Petteri Cederberg, Kati Rapia, Antti Tanttu and Nora Tapper.
Forum Box is an artist-run, non-profit contemporary art gallery located at Ruoholahdenranta in Helsinki. Maintained by a cooperative founded in 1996 at the initiative of sculptor Kain Tapper, the gallery gives art the freedom to exist on its own terms. The austere and minimalist space invites an encounter between art and the viewer. In 2026, works by several member artists will be on view at St. George Bakery in four different series.
Petteri Cederberg (b. 1976, Espoo) is a visual artist based in Helsinki. His works explore the unconscious aspects of the human mind and the logic of the subconscious. Cederberg works primarily with stop-motion animation, as well as drawing and painting.
Cederberg earned a Master of Fine Arts degree from the Academy of Fine Arts in 2011 and is a member of the Finnish Painters’ Union. She has held numerous solo and group exhibitions both in Finland and abroad. Her works are included in the collections of the National Art Commission, the Helsinki Art Museum, and the City of Jyväskylä, among others. Her animated works have been screened at numerous film festivals in Finland and abroad.
Kati Rapia is a Finnish visual artist who works with drawing, photography, comics, collages, and animation. She graduated from Aalto University. She lives and works in Loviisa and Helsinki. She was awarded the State Prize for Comic Art in 2018.
Antti Tanttu (b. Malaga, Spain) lives in Espoo and works in Helsinki. Tanttu studied at the Academy of Fine Arts 1984-1989. In addition to his own artistic work, he has taught and continues to teach at several art institutions, such as Aalto University and the Academy of Fine Arts. In the years 2003-2009, he worked as a professor of graphic arts at the Academy of Fine Arts. Tanttu works with several different mediums, such as drawing, graphics, photography and film/video. The main focus is in mixed media and woodcut works as well as video works. In the works, layering is conceptually, content-wise and materially important. The central theme of the works is loneliness and its various manifestations. He does not describe or illustrate loneliness as such, but seeks the feeling of undivided loneliness. Tanttu explores vague sensations which are familiar and strange at the same time.
Nora Tapper
“I am a sculptor based in Helsinki. I work with wood in its various forms: sawn boards, planks, plywood, hardboard, young tree trunks, etc. A characteristic feature of my sculpting is the construction of a sculpture from individual pieces. My sculptures often depict a concrete space. My sculptures are various observations on what it means to be human, on buildings, nature, the atmosphere, and the landscape. My most recent sculptures have been inspired by medieval wood carvings I have seen in churches and museums.”
