Infinity mandala

This (glueless, of course) modular mandala uses a simple unit that can connect to its own mirror image in a way that allows you to reverse the direction of the curve, making not only circles but s-shapes, ∞-shapes, ⌘-shapes, and more, all with the same unit. (8 units with the same chirality make a circle.) I believe this is unique (or at the very least very rare).
