Made of ceramic tiles projecting from an illuminated background, Rogier Sterk’s Tiled Wall offers users an opportunity to play with light. Each tile is attached to a mechanism that allows it to be pressed and released. A tile left untouched appears to be lit only around the edges. Once a tile is pressed, however, the underlying light shines across its surface, emitting a reflection. The amount of light emitted is therefore determined by the position of the tiles.
