In Lumière Noire, the player builds a structure with fluorescent polystyrene cubes, revealed in ultraviolet light. Thanks to a camera, the computer films this structure and reproduces it on the screen. Based on the construction games of childhood, Lumière Noire encourages the player to constantly repeat the same sequences: build a building, keep it in balance and then destroy it. Indeed, depending on the configuration of the structure, animations are played on the screen when the player destroys it, thus rewarding him for his efforts. Lumière Noire is based on a paradox, since to "win", the player must destroy the fruit of his labour.

The darkness, accentuated by the fluorescent colour touches of the cubes, in which the installation is immersed, as well as the simplistic graphics of Lumière Noire, project the spectators into a childlike and dreamlike imagination.
