(NEWS) — Daniel Kish is completely blind but can still manage walking, hiking and even riding a dirt-bike by himself.
He does it by using a revolutionary “bat-like” ability known as “Flash Sonar” to create a special picture of the world around him using clicking sounds made with his tongue.

"I’ve been using it for as long as I can remember," Mr Kish, who lost his eyesight to cancer at just 13-months, told news.com.au. "For me, it was a form of seeing, but using sound."
