We are artist couple and we share our creative work completely. Our collaboration began in 2006 with the Master degree exhibition at Aalto University of Design, Art and Architecture, Helsinki. Our first museum exhibition as a duo was held in Museo Ex Teresa Arte Actual in 2008, followed by exhibitions at Diego Rivera Anahuacalli museum and Polyforum Siquieros in 2009. We then ran own art space, Invalid Robot Factory, in Neukölln, Berlin until 2013. Couple of years we sailed on Baltic sea researching relations between art, robots and sea. Since 2018 we have established Isorättyä artist Studio where we create and produce our large public space sculptures and art robots. We have exhibited internationally in galleries and museums, including Kobe Studios; Ierimonti Gallery, New York City and KIASMA Museum of Contemporary Art, Helsinki. In 2017 we were nominated for Finland’s Ars Fennica art prize. Since 2018 we have completed various public art commissions in Finland.

is a playful artwork that features three robots getting wasted at a bar. Two of them talk shit to each other, and the third one recites poetry.

Love Gear 2023

Aalto University, Espoo Finland

Materials: Wood, Stainless steel, copper, glass, electronics, mirrors 

Size: Width 2,6meters, Height 4,6meters.


Lovegear is a playful artwork where the key themes are the scales of mechanical and digital engineering and the beauty of machines. The movement of the non-human-like machine is still strangely familiar and produces emotional response in us touching the uncanny. The artwork creates an illusional effect into the façade of the building by opening a tunnel to eternity in dusk and reflecting the forrest in the front at dawn. This way  flora steps into relationship of man and machine.

Mechanic wolf 2018 konst museet i norr_edited.jpg



Robotizised sculpture: taxidermy wolf, dna test, mixed media.

The material starting point of this work is a taxidermy wolf, which had been used for biology instruction until the 1990s. 

We found the wolf in the basement of an abandoned school and sent samples of fur and a molar to the University of Oulu for genotyping which revealed that the wolf had lived in a wolf pack in Inari Lapland of Finland more than 100 years ago. Inari region there are no wolfpacks for the harm of reindeer farming

Nature Morte Web_edited.jpg
Nature Morte Photo Pirje Mykkänen.jpg

Material: surgical instruments, wood, acrylic glass, electronics, flowers.


Nature Morte is a multi-dimensional kinetic installation that lives betwixt and between the tensions of contemporary life and its uncertain relationship to the one beyond. It calls to mind the ambiguous relationship of the human to the mechanized and is rooted in the reuse of materials as an expression of the power of a transformative process that reflects the memory of a discourse
with our collective past. The installation encourages its audience to befriend the anxiety of the unknown, simply by inviting them to participate in it. This garden of life, and potentially the afterlife, is labyrinth-like in structure. It is composed of real and mechanical flowers and over 80 kilograms of surgical instruments, rife with their own rich histories of use, donated by the surgeons of the Länsi-Pohja
Central Hospital in Kemi, Finland. The participation of the visitor in Nature Morte is key to the conceit. The scalpels, clamps, needles and surgical tools respond to the presence of the viewers. Ultimately the deeply profound and playful Nature Morte, is a reminder of the opportunity of consciousness, hope and transcendence found in art to guide us in letting go of fears and embracing life in its fullness in the midst of an imminent and uncertain future for our contemporary world.

 Electromechanical sculpture.

Materials: solar panel, drift wood, electronics, metal, plastic.

Size: 1,6 x1,4 x 0,5 meter.

Electromechanic installation

Material: IV lines 1224 pcs, hoses, waterpumps, metal 

Size of one flower height: 4 meters; lenght: 5 meters; width: 5meters


The IV lines used as the material for the piece come from eight-year-old Lilja Widenius. Lilja has a rare disease: her body cannot break down fats, which is why she cannot tolerate being without nutritional intake.  Part of the treatment for this condition is a nightly IV drip. At night, when Lilja is going to bed, her parents connect an IV line to a small port placed in her abdomen. This ensures that Lilja gets the nutrients she needs while she sleeps. In the morning, her parents clean the disposable plastic line and store it as material for artwork. This treatment will continue throughout Lilja’s growing years. With the treatment, Lilja is a healthy and happy girl. The disease and its treatment were discovered some twenty years ago, before which it invariably resulted in the child's death.

We will expand the Lilja’s Garden work as more IV lines used by Lilja are collected. The work was exhibited for the first time at the Mäntta Art Festival in 2016. At that time, there was one Lilja Flowersculpture. The three Lilja’s Flowers on exhibit at WAM are compsrised of 1,224 IV lines. Water flows through them like the water veins in plants that are also part of their communication system. As artists, we find the story of Lilja and her family to be a powerful metaphor for the well of strength that people, often unconsciously, draw from to maintain their mental well-being. The significance of this mental resilience is particularly highlighted in unforeseen and difficult situations that challenge people's habits and thoughts.

Materials: Tuna skin, wood, water pumps, electronics, plastic tubes and bottles. Size: height: 2,5 m; length: 4 m; width: 0,5 m.


The Mermaid imitates japanese puto dance. The movements are powered by liquids running between the bottles. During this dance, the Mermaid pumps air with its heart to an air pillow and then releases the air so time to time it sings a melancholy sigh.

Materials: Stainless steel, concrete, stainless steel wire. 

Size: Width 12meters, Height 6meters.


Interactive monument.  The railings on the upper level have bass strings that can be played.

The monument was commissioned by the city of Pori to honor Jyrki Kangas, a versatile influencer in cultural life, who was one of the founders of Pori Jazz and worked as the artistic director of the festival for a long time.


Monument is inspired of Jyrki Kangas being a great visionary and his way of fly in his ideas as well as the state of flow created in jazz musicians' jams. The wings and the sound world they produce refer to Jyrki’s own instrument, the double bass.
