Madison is a ongoing effort to provide high quality access to modern and effective computer technology for individuals who are blind and have a severe limit on mobility or control which limits the use of standard input technologies. It bases input on a joystick and three switches. The joystick can be thought of as a navigation aid like the cursor keys up, down, left, and right. An expanded Morse (eMorse) code is used to replace the keyboard; the three buttons represent dot, dash, and meta. Applications are installed on a graph filesystem. Each filesystem node has up to four vertices, named north, south, east, and west. Navigation is done via joystick or eMorse input. Applications are deployed as jar files which are retrieved by the Web or local disk.
Yet Another Time Machine is a command line Ogg Vorbis and MPEG audio player with the ability to control the tempo of playback without changing the pitch. Primary usage would be to listen (for example) to audio books at 150% tempo. This is still understandable and saves time, hence the name of the program.
