Dumb Idea of the Day

Some really smart people have come up with the stupidest thing I've ever heard of...they have created a new authentication tool called EarEcho. Get an ear infection or let your ear wax build up and BAM! Authentication fails. Lose your headphones (which most of us are known for) and you are totally screwed. The kicker, they don't even work to play music or cancel noise. Now you are carry ANOTHER set of headphones with you.
