Light 5+5 is a rather beautiful shape-shifting lamp inspired by the excellent Rubik's Snake, first introduced in the early 1980s.
From the maker, Oikimus:
The lamp case is made of plywood. The light's source is LEDs laid inside the case illuminating through frosted Plexiglas. The "5+5" lamp can be used both in public areas (cafes, restaurants, hotels, shops, etc.) and in the residential houses. The main feature of the project is its versatility: thanks to its size, practicality and ease of assembly, it can be easily transformed into a table lamp, a wall lamp or even attached to a ceiling.
