It’s called “CRUDA” I thought the stone bases as the only decorative element does not “designed”, but borrowed directly from nature, (potentially a person could choose their own stone and make the object really unique).
In the stone are inserted two cables (for the two polarities) 3 mm copper and covered by a polymeric paint so as to isolate them and to avoid possible short circuits by touching one of them.
Two clamps on the cables are inserted in the first power cord is plugged in and connected to the second I OLEDs.
