Here is a scene with three rings constructed in different ways:
One ring is a BezierCircle with Simple deform and Solidify
modifiers.
Another ring is a Mesh with Array, Curve, Solidify, Bevel modifiers.
And the last ring is a Mesh with Subsurf, Skin, and another Subsurf modifiers.
small game; guess how the ring was built.
I took you up on your guessing challenge, but I downloaded the blend first to get a close-up of each ring. The bezier one was easy to guess and I managed to work out the most logical method for the other two. This was an interesting blend to study.
I'm very grateful that you're sharing your blends on Blendswap.
