The American Printing House for the Blind, or APH, has been a Louisville institution since 1858. Not only does the non-profit organization provide braille textbooks and other educational aids through the Act to Promote the Education of the Blind, its research department also develops new technologies.

One such device, a prototype called Graphiti, helped students and adults who are blind or visually impaired experience Monday's solar eclipse in near real time. According to APH, that's never been done before.
