French designer Jean-Sébastien Lagrange has created a cross between a poster and a lamp.
LEDs illuminate when a magnet at the bottom right corner is folded up to another, connecting the start and end of a conductive ink trail to complete the circuit.
Jean-Sébastien Lagrange claims that anyone can create the posters by printing the ink onto a sheet of paper in this graphic pattern.
The LEDs are scattered along the snaking pattern of the ink lines, with a row of the tiny lights running along the gentle fold to create a glowing uplight.
The bottom of the sheet is cut at an angle so it appears horizontal when the magnets are attached and wires hang behind the poster to connect the circuit to an electricity supply.
Other lights that use magnets include a magnetic concrete lamp and bike lights that turn on at contact with the frame..
