Lance Corporal Craig Lundberg lost his sight to a rocket-propelled grenade in 2007. Now, thanks to a fascinating technology, he can read words and make out shapes using his tongue. It's truly incredible.
BrainPort, created by neuroscientists at Wicab, Inc., may allow the blind to restore part of their sight by routing sensory information through a different receptor. Using a digital camera and specialized "lollipop", the blind can actually see with their tongues.
