The project interprets the normaly invisible electronic components of LED’s in an abstract way. The installation makes clear that there is a plethora of essential components between the actuation of the light switch and the illumination of the room. Consciously the choice fell on the commonly known circuit symbols, such as the crossed circle (Lamp). Even if these are partly outdated, they are understandable to all. The illustration shown initially shows, by way of example, a manageable quantity of components, which can be expanded as desired. According to the building block system, sculptures can be created that integrate into existing architectures or contain interactive elements.
