My idea is to use the $5 Pi Zero as the brain for a game system for the visually impaired. Interaction would rely solely on sound and touch. The system would be very inexpensive because it requires no expensive screens! :-) Just a $5 Pi Zero, a speaker, a few pushbuttons, and possibly a microphone. I have a few game ideas in mind. I will share in build log of this project as those ideas become clearer in my head.
