Given that a bangle is nothing more than an over-sized ring, why is it that puzzle bangles are virtually non-existent while puzzle rings are easy to find? It's a mystery to me.

GALLIC is the first of my rings to be scaled up to bangle size, but it certainly won't be the last. For one thing, I want to have at least a few ring/bangle sets, and for another bangles offer more scope for experimentation than rings, simply because of their greater physical size.
