Daniel Kish is blind and he navigates the world kind of like a bat—making clicking sounds with his mouth and, from the echoes he gets back, building a picture of the world he's moving through. "The sonic environment is incredibly alive," says Kish, who lost his eyes to cancer when he was barely one year old. He doesn't just get around. He reveals in the physical beauty of the world. "Domes are pretty special," he says. "So I've been in these tropical gardens, for example, where they'll have these dome structures over these gardens. And when you find the apex of the dome, your every sound that you make, and every sound that's being made in that dome is highly, highly resonant." Come along with us while we walk alongside one of the world's leading experts on echolocation. Part 1 of 2.
