It’s been awhile since we’ve seen a cool ring. This may be the coolest we’ve seen yet. This gear ring from Kinekt Design does more than just sit on your finger. It spins. The ring is made completely out of stainless steel, with six internal gears that spin with the two outer ones.
It’s simple and elegant design. It’s currently available in US sizes 9 through 12 for $165. It should definately impress all your friends and most importantly the opposite sex. Check out a video below of the ring in action.
