Each of these halo-shaped circles is an independent LED light fixture that casts a round ring of light on the wall. What makes them more interesting, however, is the way they can be combined into more complex shapes to create decorative patterns.
A simple singular Flos Architectural Wall Piercing ring creates a flower-like arrangement, while an untidy line adds some asymmetry into the mix.
They can be layered up and interlinked as well, though the effect starts to overwhelm the viewer a bit (perhaps more appropriate for a night club than a living room) if the patterns become too pervasive.
While they are attached to the wall, they look like hoop earrings actually piercing the surface from a distance – or as if someone stuck the each ring in while the plaster was drying. Definitely a neat effect and is multiplied through creative combinations and overlaps.
