We are very happy to announce that Collective Mindscape is now open for viewers at Comprehensive Cancer Center. 

Eight participants described their two inner landscapes to the us: their personal sanctuary, and the more difficult terrain, which reflects life with cancer. The mindscapes were realized with 3D graphics and combined into one virtual world.

The artwork is displayed on a framed screen, which in passive mode looks like a large slow-moving landscape painting. You can dive deeper by sitting in front of it: simple instructions on how to move in the terrain appear. 

If you want to hear the thoughts and experiences of the participants, you should look for particles of light in the terrain: walking through a shiny cloud makes the participants talk about their cancer experiences and their relationship with their mental landscapes.

Common Mindscape has been realized using the open world game technology. The visualization of the work is made by 3D artists Vilma Ratinen and Katariina Kontturi.

Common Mindscape  is the result of five years of work. The piece is part of a collection of commissioned works for the hospital Encounters – art in Siltasairaala, curated by Taru Elfving. Common Mindscape  is the first media artwork in the collection involving patients.

We first designed the piece for cancer patients, but have later understood that we all belong to target group.


“THE BALLOT” is an exhibition about a small but highly significant artefact: the ballot paper. Taking place during the time of the Finnish parliamentary elections in 2023, the exhibition tracks the evolution of the ballot paper in Finland, the other Nordic countries, Germany, and Lithuania by presenting 60 historic artefacts from 1856 to 2021.


Why do the ballot papers look the way they do? Who actually designed them? How come the ballots are so different between countries with similar political systems? How do ballots reflect political trends and events over time? Is the current ballot design the best we can do or is there space for improvement?


The evolution of the Finnish ballot started with one of the most progressive electoral laws in 1906, featuring oversized, so-called bed sheet ballots. Starting in 1945 Finland switched to one of the smallest ballots in the world, nicknamed appropriately the miniature ballot, which is still in use today. Even though this ballot paper has passed through the hands of most Finns, it is hitherto unknown who actually designed this innovative ballot. The exhibition can provide a likely answer to this question.


The opening event takes place on March 15th at 17:00 at Nordic Culture Point in Kaisaniemi.

Come and check out exciting ballots from Finland, Germany, the Nordic countries and beyond.


The opening will also feature an entertaining panel that will deconstruct ballots live on stage. Three experts from different fields of knowledge, such as UX design, democratic governance and art will pass judgement on a number of ballot contestants. Further events are especially catering for young and first-time voters.

TUE 30 AUGUST 2022

On 30 August 2022, Lönnström Art Museum and Studio Kalleinenwill present and launch the English version of Conversation Park; a book exploring an in depth overview of a unique artistic experiment in transforming an abandoned plot of land into a public park in Rauma, Finland. The book, which is for sale at the event, is written by artist duo Tellervo Kalleinen and Oliver Kochta-Kalleinen, and co-edited by artists, curators and researchers Miina Hujala and Arttu Merimaa.

At the book launch in PUBLICS, Tellervo Kalleinen & Oliver Kochta-Kalleinen will introduce Conversation Park project followed by response from prominent Finnish researchers on participation – Kaija Kaitavuori and Robin Lybeck  – providing additional commentary and insights with respect to their expertise on participatory art and participatory urban planning.

In 2019 thirty residents between 6 to 89 years old became players in a two-year-long “Public Space Game”. The mission was to turn thirty individual ideas for a park into a collective urban reality in 6 game moves. The cooperative park was opened in 2020. Conversation Park is a Lönnström Project and made possible by the Lönnström Art Museum in Rauma.

In the book Kalleinen & Kochta-Kalleinen describe their original intentions when designing the game and share their insights gained whilst working on the Conversation Park for four years. The book touches on core questions with regards to engaging citizens in designing urban public spaces. It is an attempt to open-source the Conversation Park project so it can be analysed, modified, and replicated. It is an invitation to learn about the many factors which have to be considered when designing a participatory project – whether it takes place in art, urban planning or politics.

Helsinki-based Tellervo Kalleinen and Oliver Kochta-Kalleinen are an artist duo whose practice merges the languages and approaches of multiple disciplines, such as film, performance, game design, experimental education, facilitation, social architecture and alternative economies.

Robin Lybeck is a researcher at the sociology department of Åbo Akademi  University. He has studied typologies of engagement in urban planning. His PhD looks at how technology is applied in the context of participatory planning and urban development.

Kaija Kaitavuori is an educator and art historian. Her research focuses on audience participation in contemporary art. Her dissertation “Art of Engagement” discusses participatory processes in terms of democracy and the extent to which participation in art can be understood as ‘democratic’.

BIASED @ Espoo City Theatre 12 – 19 May, 2022

A performance @ Espoo City Theatre, Espoo, Finland

People mostly believe their thought processes to be both rational and sensible. And yet, systemic mistakes influence our thinking far more than we realise. These universally shared mental shortcuts are known as cognitive biases. The best-known cognitive bias is the confirmation bias which leads us to select information that supports our existing views. BIASED invites the audience to explore these hidden notions and unconscious factors that drive our actions.

BIASED is born out of collaboration between five artists. Matija Kezele from Croatia, Fred Nevche from France, and Tellervo KalleinenOliver Kochta-Kalleinen, and Anna-Mari Karvonen from Finland explored the theme as a part of Espoo City Theatre’s contribution to Centriphery project.

It is now possible to get to know Keskustelupuisto (Conversation Park) through a mobile phone app! It is currently only partly in English, but please have a look and get a sense of the project, where 21 inhabitants of Rauma negotiated and realised a new park together from the scratch. In the app the participants introduce the park, and you can hear in depth interviews with them before and after the 2 year park making process. Some of the features work only at the park, such as the park disco. You can download it for free from play stores: the name of the app is Keskustelupuisto. Any feedback welcome!


In June the boss of Y-Foundation contacted us, asking if we’d like to make a new art work for their 35th anniversary. We had never heard about Y-foundation but learned soon that it is a a non-profit and independent foundation, who builds / buys and renovates houses, which they then rent for people who have low income – as inexpensive as possible. Y-Foundation have developed the Housing First principle, which means that one needs to have a home first before sorting out other issues in life, and thanks to this simple but powerful principle, during the foundation’s 35 years, homelessness has went radically down in Finland. Inspired by all this, we developed an art work Ode For Y, which consists of 17 374 mosaic tiles. The mosaic will have an augmented reality -layer, turning it into a sound piece. We invite tenants of the Y Foundation’s 17 374 flats to give their voice for one of the mosaic tiles! (Part of the difficulty of reaching the tenants is that many of the renters don’t even know that they live in an Y-foundation flat) Here is the link for participation!


Happy New Year! We hope you are well and healthy. We are currently working on two new commissions, which we look forward to tell more about soon. In the end of January 2021 we start to make a 3D demo for one of the projects with 3rd year students of Metropolia University of Applied Sciences, and we are excited about this collaboration. Also Centriphery – an EU project, which we make in collaboration with Espoo City Theatre, Finnish director Anna-Mari Karvonen, French musician Fred Nevché and Croatian actor Matija Kezele, is taking an exciting direction after many discussions and co-planning. Looking forward to share details on that as well as soon as possible! The performance will take place in Spring 2022. We are working also on another performance piece, which will take place in Belgium this year – more info will follow from that as well! Stay safe, wishing you good spirits!
