This Armillary Sphere Ring is a variation on one pictured in Historic Rings by Diana Scarisbrick. The original opens out at a 90 degree angle to the outer ring, but I can never leave well enough alone, and I figured a shallower angle would evoke more of that armillary sphere effect that she claims was the point of the original.
