The Mercure Lamp is a tactile, interactive lighting design by the French designer Lucie Le Guen.
This lamp is inspired by the mercury tilt switch, inside of which a drop of mercury switches the light on and off depending on its inclination.
When the lamp is tilted to one side, the marbles within slide towards the base. This connection between the two metals completes the current needed to illuminate the bulb. The movement makes the inner workings of the object visible. In the era of touch command it is necessary to understand the importance of the intention of gestures and how to best design for them.
