I dunno. I think, though, that it's gotta take someone with some serious cajones to walk around a major city... hell, even a small town, blind. That's someone with some serious nerve. My hat's off to 'em.
Reminds me, though, of when I was at the new employee orientation at my current company. I'm in this conference room, and this one guy's passing around some work his group is doing for a project for the Canadian government. Web pages in braille, believe it or not.
He passes around the braille printout of the web site, and, when it gets to me, I run my fingers over it (yeah, like I can read braille), and I just can't resist... "Oh my god, this is a porn site!!!"
Well, I thought it was funny.
