LUMEN is an interactive, immersive audio and video display system. It consists of rear projected screens arranged in a 3x3m cube and controlled by an old-fashioned oil lamp.
You can discover various invisible objects floating around in a virtual environment. You cannot see them, but they do cast shadows onto the walls of LUMEN, when moving the lamp, the shadows of the virtual objects behave like you would expect, giving you the ability to locate those objects. Whenever you enter one of them by holding the lamp in its location, you virtually step into the object and reveal its content.
