This wooden coaster is composed of 9 concentric frames where each frame is stuck into and rotated within the next frame - thus forming a twisted affect on its surface. The grains rotate together with the frames and this creates a strange lighting effect on the surface: some elements look brighter, while other look darker, however all the 4 elements bear the same color. The elements stick together like marquetry pieces.
This coaster is laser cut from 4mm birch plywood board, hand polished and oiled.
These rings are available at the following marketplaces.
