Well, I won't be entering this contest, but I've received some email from a blind user of my software and I'll be trying to work in some accessibility in a future version.
It won't be easy to start, but this is something that has always been on my mind. Until I got that email though, it was a VERY distant priority.
Fortunately he gave me some resource links to find out more so that I can work it in.
While good eye-sight is something a lot of us take for granted, not everyone has it. (I believe that it can be partially fixed by smoking marijuana, but if I'm wrong you'd at least have fun trying.)
But honestly, I had no idea that there was an entire genre of games out there like that. (But I don't play games either - they're more addictive than heroin.)
In any event, good luck to the participants and may the most fun game win!
