Fidget toys have grown incredibly popular over the last year, but not all fidget tools are created equal. The best "fidgets" are those that are silent and not distracting. They occupy users' hands and their "floating attention" but not do not draw focus from the more important tasks at hand. SwingOs do just that. SwingOs' three stacked rings, pivot and rotate in endless circles and are as intriguing as they are pleasing. The three rings are seamlessly attached to each other, and rotate around each other in surprising and various ways. Grip the rings, or slip a finger in any of them, and swing away with abandon.
