Nir Meiri made the lamps by draping fresh seaweed over a structure of thin metal spokes attached to a metal base, says Helen Buckle in her article on Dezeen.com. The final shape of each lampshade is formed as the seaweed dries and shrinks, before being set with a preservative. Marine Light was presented at Spazio Rossana Orlandi in Milan last month. Other lamps on show included a light with coloured LEDs in red, green and blue to cast shadows in cyan, magenta and yellow and a folding lamp powered by little wind-up keys.
