Since we are on the subject of modular lighting – consider this incredible design idea. The Guss lighting system by designer Santiago Sevillano has countless number of possible configurations. Its identical curvilinear segments can be rearranged into any light-related object of your choice. With Guss you can build pendants, wall lamps, table lamps, floor lamps, you name it!.. And the lamps are eco-friendly too, they consume 80% less energy than standard incandescent lights.
