Tyyni is an experiential sound and spatial installation that draws on the height and spatial expanse of Öljysäiliö 468. The installation's circular form encloses an interior space of its own within the tank. Sheer fabric, stretched across aluminum pillars, descends like sand dunes, forming the installation's dominant visual theme. The fabric's translucency and the interior lighting create a soft, sand-like surface that responds to shifts in light and sound.

Tyyni is set among sand dunes and draws on mountain meditation, at whose core lies ever-changing weather. The installation's sandstorm and the dune's stillness serve as a metaphor for shifting emotions and thoughts: they intensify, then subside. The sandstorm shapes the dune's surface, breaking and battering it, but the dune always returns to stillness, as if nothing had ever happened. An emotional storm works the same way.

Drawn from the expansive architecture of Öljysäiliö 468, the exhibition explores the effect of space on thought. It is grounded in the idea of the cathedral effect, which holds that tall, open spaces support freer, more abstract thinking.
