Art duo Grönlund-Nisunen (Tommi Grönlund and Petteri Nisunen) have been working together since 1993. Technology, sound and light are the base materials of their work. The artists examine issues such as space and physical phenomena. Their sophisticated installations often play with the physical laws of nature and explore sound and space in a modest, low-tech manner. Originally trained as architects, their examination of urban/social space and nature still makes up a large part of their work. In addition to numerous solo and group exhibitions, they have also completed major commissions in public spaces.
In their new piece titled Unstable Matter, several thousand steel balls have been placed on a 150 x 150 cm large metal surface, which subtly tilts from one side to the other. Depending on the inclination angle, the balls begin to roll to the lower edges, continually forming changing patterns. The natural sound of the steel balls rolling back and forth creates a zen like sound of waves moving in and out of the ocean, reminding us all that life can be calm at one moment and yet shift at any given moment.
