I once saw a show about a boy who was blind from birth. He somehow developed his hearing to an amazing level. He would make clicking noises with his tongue, and listen to the reverberations to make a mental image of the world around him, and navigate around like any person. I thought the news show this was on was bogus, but after doing a little ad-hoc research about it, I discovered to my amazement that it is a real case, and not the only one at that. The program also had video footage of him riding his bicycle around town.
