This file contains a script which let you generate a circular array of objects around the 3D cursor, duplicate linked, with objindex incremented. Then by using a driving the led material, it turns on the leds depending of the rotation of the knob.

Recently I realized that lighting is not just a lamp on the ceiling, but the mood of the entire room. I was looking for something unusual and accidentally found myself on the page of Victoria Yakushi's lamps https://victoriayakusha.com/collections/lighting . Each item there seems to be created to emphasize the character of the space: smooth lines, natural materials, soft light. Looking at these models, you begin to believe that light can be a real art, and not just functionality.
