If you’ve not seen this ring yet, you’ve definitely got to check it out! Not only does it look cool, it’s also very addicting to play with. Both the outer races rotate, simultaneously rotating the little gears along the center. It’s quite impressive, which is why I have one of my own. Created by the talented Glen Lieberman and his company, Kinekt Design, you can get your own through their website as well as see a video of this thing in action!
