For the Saint-Etienne International Design Biennial, Jean-Sebastien Lagrange teamed up with graphic design studio Chevalvert for a project that reinterprets our usual sources of illumination.

L-Ink, a hybrid between a lamp and a graphic poster, uses silver-based conductive ink to join 40 LEDs placed strategically on a plain sheet of paper. The poster starts emitting light only when a magnet at the bottom right corner is folded up to another, closing this way the ink circuit. Electricity comes from the pins that hold the top of the sheet, which are connected to a plug.

Although L-Ink is mainly a research project rather than a commercial one, Lagrange says he had in mind a design that could be reproduced by anyone, with the right technology at hand.
