I saw this advertised in one of those late night infomercials. Not sure what made me look up from whatever it was I was reading, but when I did, I had to go online and check it out.

The Gear ring by Kinekt Design is made of stainless steel and is exactly what its name says – a ring with moving gears. The inner gears turn when the outer rings are spun. For a fidgety type like me, perfection. Jewellery you can play with is always fun and this ring appeals to the geek in all of us. Also a perfect gift for guys who may be into gadgets and tools but not jewellery.

Available from Kinekt for USD $165.
