Actually, since we're getting pedantic here, concentric circles in a 2D space like Hotaru's irises are actually mathematically continuous, not discrete. And '' rinne''gan specifically alludes the Samsara, symbolizing an eternal cycle, as does the spiral powered individuals eyes, since both concentric circles and spirals are used to represent infinity despite the fact that they're not the exact same graphic symbol. In fact, optical illusions like Fraser's twisted chord plays with the fact that under certain circumstances, concentric circles and a spiral appear optically the same.
