Version 3.0.0a now available for download

WinTriangle is a scientific word processor the blind, developed by John Gardner at Oregon State University. This program allows blind or visually impaired users to read and write complex mathematics -- it serves the role of pen and paper for a blind mathematician or physicist. Sighted people can read the output in Word once they have installed the font files, Triangle.ttf and MTExtra.ttf. Users of WinTriangle can read LaTeX files by converting them to Triangle with LaTeX2Tri.
