The Tic-Tac-Toe game inspired us because it’s simple, at hand and fun. As amenity and space, OK Center is not just a location for classes: it is an anti-boredom place, open to dialogue and directly involved in the learning process. Space speaks of itself, about the materials it is made of and its connection to the world: installations and raw building materials (concrete, plaster, wood) are intentionally visible. The user can touch, perhaps understand where the yellow pipe comes from and where it goes, learn the source of the wood for furniture and the cost of the bench he is sitting on. Simple materials such as concrete and wood are strategically duplicated by large splashes of color in order to gain a strong visual impact.
