Inspired by the four classical elements, earth, air, fire and water, Nacho Carbonell has incorporated subtle references to these through the design of his hand made lightbulb. In an ingenious way, water in the bulb creates a sea-like light reflection from the light source, (the representation of fire) into the environment where the bulb is placed.
Additionally, the user can interact with the lightbulbs size by pumping air into the lightbulb, another reference to an element.
