Kinekt Patented Moving Gear Ring

This high-quality stainless steel ring is for sale at Kinektdesign.com with a lifetime warranty  for a mere $165, and here is what they have to say about it:

"The patented Gear Ring is made from high quality matte stainless steel. It features micro-precision gears that turn in unison when the outer rims are spun (as can be seen in the video)."

Two words.  Absolutely. Squee.

You may read a review of this ring on The Gadgeteer.  This bloke did a video of his new ring, from un-boxing to lots of gratuitous rotating of the parts.

That is all!
