“Stop playing with your ring!” This is something you have probably all heard at one time, as you twiddle away with your fingers and annoy the hell out of the people around.

Well, those intolerant fools can suck it: the Kinekt Gear Ring is *made* for playing with. The surgical steel circle has two bands running around the outer edges with teeth that engage six tiny cogs that spin between them. These cogs mesh with the teeth and make a finger-band that will be impossible to stop spinning. Want to see a video of it in action? Sure: Kinekt Gear Ring video (.mov). (Sorry, the embedded video we had here earlier disappeared.) Update: We found another one on YouTube. Thanks, Rachel!

The ring will cost you $165, Buying one as a gift for a geek-in-law is like buying a drum-kit for your nephew: the giftee will love you. Your sister will hate you.
