DEMI-RHOMBI is a reconfigurable origami lamp that can be installed as a ceiling lamp as well as a table or floor lamp. DEMI-RHOMBI is based on scientific research conducted by physicist dr. Ir. Bas Overvelde and In the year 2017 was published in the magazine Nature. DEMI-RHOMBI is inspired by the structural diversity and foldability of prismatic geometry that can be built using origami techniques. DEMI-RHOMBI is in the nucleus a so-called cube, a Platonic-Body. Three of the five Platonic bodies (the cube, tetrahedron and the dodecahedron) were first described by Pythagoras around 550 BC. One and a half centuries later (427-347 BC), Plato described the other two bodies: the octahedron and the icosahedron.
