ABSTRACT:
The present invention provides a novel interconnected ring toy effective in reducing the physiological and psychological effects of stress and in improving manual dexterity. The toy is comprised of a plurality of interconnected rings, each ring interconnected with every other ring, the number of rings, ring diameter and ring cross-section chosen to define that amount of free space between the rings which prevents unrestricted movement of the rings yet permits a degree of play to facilitate manipulation of the rings with respect to each other.
