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.
Free admission

Petteri Cederberg (b. 1976, Espoo) is a Helsinki-based visual artist. His work explores 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 his Master of Fine Arts degree from the Academy of Fine Arts in 2011 and is a member of the Finnish Painters’ Union. He has held numerous solo and group exhibitions in Finland and abroad. His works are included in the collections of the National Art Commission, the Helsinki Art Museum, and the City of Jyväskylä, among others. His animated works have been screened at numerous film festivals in Finland and internationally.

Kati Rapia (b. 1972) received her Master of Arts degree from Aalto University (Department of Photography, University of Art and Design Helsinki) in 2003. She trained as a visual artist at the Lahti Institute of Fine Arts and has also studied literature at the University of Tampere.
Rapia works across multiple disciplines in the field of art. She alternates and interweaves her working rhythm between photography, comics, and collage. She is interested in the layering of time, the drifting of materials around us, activism, and play. Regardless of the medium, documentary elements or history often serve as a springboard in Rapia’s works for explorations that reach beyond everyday life, combining fact and fiction into visions of the world.
Rapia has received a state prize for her graphic novel Pyrstötähti ja Maailmanlopun meininki (published by Teos) as well as for her “multidisciplinary art that makes precise observations of the world.” She often produces serigraph prints connected to her comic publications.
Publishing, exhibitions, and collective modes of working form the foundation of Rapia’s artistic practice. She has also served for ten years as the driving force (primus motor) of the multidisciplinary contemporary art community Loviisa Contemporary. Her works are included in the collections of the Finnish State, the City of Helsinki, the City of Turku, and the Wihuri Foundation

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 is a Helsinki-based sculptor. She works primarily with wood in various forms: sawn boards, planks, plywood, hardboard, young tree trunks, and more.
A characteristic feature of Tapper’s sculpting is the construction of sculptures from separate pieces. Her works often contain a concrete, physical space. The sculptures reflect different observations of being human, as well as of buildings, nature, atmosphere, and landscape.
Her most recent sculptures have been inspired by medieval wooden sculptures she has encountered in churches and museums.
