I remember when the Graphiti was still being developed over at the American Printing House for the Blind while I worked there.
They used an early model in combination with some form of special camera setup a few years back to allow staff, students, and visitors at the American Printing House for the Blind and the Kentucky School for the Blind to view a solar eclipse. It was interesting to see people using it. I didn't get a chance to interact with it because I was so busy that day but I watched a video on it.
There is a Lion Club article on the Graphiti, it's development, and some of the experiences it enabled entitled
$1.
Not sure on the price of it. I know they wanted to get it to a point where it could be under $5,000 back in 2020. I'm not sure if they have gotten to that point yet or not.
