The term 'annulus' is mathematical--the region between two concentric circles. That particular landscape of patterns deeply intrigues me, and this particular design lives in that world, but also in the worlds of implied circles, rhombic motifs, and a recent (and amazing) color in the LEGO world: Magenta. This particular design is quite flexible, so if you want it to be yours be prepared to take care of it each time you move it. Simple compression will keep it stable for many years to come.
