Häiriötiloja / Interferences

Ristinolla, 2025

Glass balls, LED lights, controller, power supply, stand
100 x 30 x 30 cm

A random generator switches on three white led-lights at a time. If all the lights are in one line, their color turns red. The lights are projected to the ceiling above through glass balls which function as lenses.

Turku Beat Frequency, 2025

Analogue sine-wave oscillators, subwoofers
Dimensions variable

Two beat frequency oscillators playing slightly different 50-60 Hz sine wave tones. The two sine waves interact in the space, creating a third so called interference sound. In certain spots, the sound is louder than elsewhere in the space, due to standing sound waves formed by reflected sound waves travelling to opposite directions.

Lines, 2023

Serigraphy print, oak frame
82,5 x 89 cm

3° / 4°, 2023

Serigraphy print, oak frame
65,2 x 65,2 x 4,5 cm

Employing two thin sheets of Plexiglas with a grid of small holes, the work creates a moiré effect. Using simple means and employing the physical properties of natural phenomena, the work creates a captivating yet subtle visual impression.

Spheres Tomography, 2023

Perforated Plexiglas
22 x 22 x 22 cm

In Spheres Tomography interlocking spheres were created inside a layered cubic volume by removing material. The work appears very different when looked at from different angles.

Frozen Sphere, 2023

Stainless steel sphere, refridgerant gel, freezer, plinth
Sphere: 26 cm
Plinth: 30 x 30 x 90 cm

A stainless-steel container in the shape of a sphere is filled with freezing gel. It is then kept in a freezer overnight and displayed on a pedestal during the day, when the exhibition is open. The moisture in the air of the exhibition space condenses onto the cold surface of the artwork. Because it is highly polished, and hence hydrophobic, the water tends to condense on it in droplets. The surface of the work, which is otherwise reminiscent of a minimalist sculpture, is in a constant state of slow transformation, first freezing and then melting.

Two Views, 2022

LED screen, tablet, surveillance camera application
Plinth: 110 x 30 x 30 cm

The work plays on the physical properties of light, its transmission and perception. While the LED screen seems to produce a steady glow of white illumination, the ipad--because of the nature of its technological transformation of light waves into digital information--reproduces this sight as a pattern of white and black horizontal bars. That is, the tablet camera filming the LED panel records as horizontal “interfering” lines across the image what a human eye does not see: the intermittent waves constituting the LED light. Comparable to the horizontal lines produced when filming analogue television sets, the work uses a technological glitch to highlight the nature of light and its transformation by various technological means, as well as the limitations of human perception.

Falling Water, 2020

Glass tube, stainless steel stand, plastic, tube, peristaltic pump with stepper motor, silicone oil, distilled water
192 x 38 x 38 cm

Falling Water consists of a vertical glass tube, one third of which is filled with distilled water and two thirds with silicone oil. The water on the bottom is pumped up by means of a small digitally controlled pump and falls down through the silicone oil as small droplets. Employing relatively simple but sophisticated means, using magnetism, electric currents, or simple gravitational forces, Tommi Grönlund and Petteri Nisunen create quietly evocative and formally striking works.Falling Water consists of a vertical glass tube, one third of which is filled with distilled water and two thirds with silicone oil.

Restless Horizon, 2016

Acrylic aquarium, distilled water, silicone oil, aluminium stand, bearings, attachments, electric actuator, limit-switches, control units, power source
240 x 85 x 24 cm

A large acrylic aquarium is filled to the brim with half distilled water and half transparent silicone oil. Because silicone oil is less dense than water and they are immiscible, the oil floats on top of the water with a transparent, but clearly visible borderline between them. An electric actuator operated by limit switches and a control unit slowly tilts the aquarium back and forth, creating visible wave patterns at the boundary between the two liquids. The high viscosity of the oil makes the movement of the waves slow and dreamlike.

Color Mixer, 2016

Programmed LED-projectors, powder coated steel, sand-blasted glass
2210 x 140 x 50 cm

Eclipse, 2007

Video projector, round mirror, wire, electric motor with reduction gear
Dimensions variable

Eclipse consists of a round dvd-projection resembling "Moon" and a round mirror suspended from the ceiling in front of the beam. The slowly rotating mirror casted a changing shadow on the projection and a moving light reflection on the surrounding walls. In a way the installation created its own simplified "lunar eclipse" to the room.
