Fingerprint Jewelry: Unquestionably Yours

So this isn't really gadgety or anything, but it certainly has a geek quotient to it. You send a copy of your fingerprint to fancy schmancy jewelery maker Piaget, and they'll make a watch or pendant design out of it. The swirls of your print will be laid out in diamonds and white gold, which means this thing will be uber pricey. So pricey, that Piaget isn't saying how much it'll cost — you'll have to ask 'em yourself.
