This is Pat Fletcher, and those aren't sunglasses. Pat is blind, and she's an amateur scientist. Those are "hearing" glasses she's wearing.

"For the past few years, she's been experimenting with a revolutionary new technology that allows her to see through sound. Using a simple computer program that she downloaded from the Internet, called "The vOICe", which translates visual images into soundscapes, Pat's brain is able to translate those sounds back into images."
