The Voronoi diagrams have been used in engineering and natural sciences since the 19th century. Carlos del Castillo achieved to bring the continuity of their surfaces and the beauty of their shapes to a family of lamps.

Concepts like texture, emotion, roughness, organic, rustic and traditional that are unconsciously attached to sand meet the characteristics of complexity, geometry, science, innovation, future & trend of the Voronoi pattern.

Sand and technology form these luminaires to be a modern, simple and elegant element for all living spaces. 

The main goal of this project with Sandhelden was to create a product able to teach and show what this technology is capable of doing in terms of complexity. At the same time, it studies the limitations of the technology of Sandhelden.
