I like the idea of making science accessible for all. An eclipse is one of those once in a lifetime events that people need to experience, if only so we can get a glimpse and be in awe of the wonders of the universe.
The fact that this experience can now be shared through sound is a great way to allow the visually impaired the chance to explore and discover a phenomena that used to be beyond them. It's also exciting to see how the knowledge and resources that come out of this technology can be used to further improve the quality of life of visually impaired individuals.
