Modular lighting system by Ross Lovegrove.
There's more to the Yamagiwa:Lovegrove collaboration. SystemX is an X-shaped lighting module that can be interconnected with other SystemX modules to create lighting structures. "The product can be specified for both private and public use, beginning with small dimmable configurations for above the dining table to large open expanses that can create zones of different temperatures of light in collective or singular modules.".
