Walking along the path across the Planted Roofs, stars form and then dissolve again, one after another, as the different pieces comprising them are visually assembled and disassembled depending on the specific perspective of each viewpoint. The work EFCHI [wish] is a light installation that invites us to explore the magic of perspective, as we enter a landscape of harmony, hope and warmth. The fragments that become aligned seem to make a promise that the scattered pieces will be joined together, and everything will eventually fall into place at the right time. The installation uses simple geometry rules to offer an experience that is both aesthetic and emotional, a visual play that may give rise to an optimistic thought.
