Love gadgets? You just might fall in love with this fantastically addictive ring I came across the other day. Made from high-quality matte stainless steel, the Gear Ring from Kinekt Design features six micro-precision gears that turn in unison when the the outer rims are spun … in short, a fashionable and fun new toy.

It’d definitely make a cool wedding band for someone looking for something really nontraditional, but I think it’d be a great gift for your best man, too. At $165, it’s definitely for someone special, whether it’s you or the guy or girl who puts up with you!
