Geometric Lights - Interlocking Quadrilaterals

Geo-Lights.  Puzzle Lights. Interlocking Quadrilaterals. All these refer to the lighting concept invented by Danish  designer Holger Strom. By interlocking quadrilaterals, he discovered it was  possible to create lanterns of various shapes and sizes only by linking together the identical elements of a basic rhombus. Holger and his wife live in Denmark where they continue to sell their beautiful lights.
