The construction and function of this wall light are highly poetic, calling to mind the well-known game of tic-tac-toe. It is possible to create personal arrangements in which the intensity of light emitted can be modified by selecting the number of crosses to be illuminated. The basic set comprises 5 crosses made from matte black injected polycarbonate which are backlit by LEDs and clipped into a double L-shaped matte black lacquered steel wall frame. Each set may be used on its own or may be combined with up to 6 others. Each additional set may be connected to any cross already installed. The possibilities for creating installations become limitless. Each cross turns 45°: a turn to the left will switch off the current, while a turn to the right will let it continue. Because of this flexibility, a multitude of light trails may be created. The first cross serves as a general on-off switch.
