Ring and Cylinder Installation for a Riyadh Cultural Atrium

The atrium is the first interior guests see after security. The architect wanted a piece that could be read from three floors at once, without blocking daylight from the skylight. We composed concentric brass rings with a field of suspended opal cylinders, each on its own drop length taken from a laser survey. All rings are 2700–3000K tunable white, DALI-2, with a daylight-linked scene that holds the cylinders just above the ambient skylight so they never look dull at noon. Cylinders are hand-blown glass with a brass cap and a replaceable LED engine. The installation was trial-hung in our Zhongshan hall against a taped floor plan, then shipped as a numbered kit with a rigging drawing for the local contractor. Two commissioning nights locked the evening scene that now photographs as the project’s identity image.
