Blind Soldier Uses Tongue To "See" 107 107

Zen found this story about a blind soldier using a lollypop-sized tongue sensor to 'see.' The system actually enables him to walk and read unaided. The guy says, "It feels like licking a nine-volt battery or like popping candy. The camera sends signals down onto the lollypop and onto your tongue, you can then determine what they mean and transfer it to shapes."
