  1. David Heise and Tomas Joynerpresents Prograph Not Just Another Language

  2. Visual Languages • An Evolution • DOS --> Windows • Text --> Graphical • Concept • provide a more intuitive mapping from an algorithm's concept to its program

  3. Prograph • Invented by Tomasz Peitrzykowski and Philip T. Cox in 1983. • Visual Language primarily for the Macintosh. • Based off a combination of Lisp and Prolog.
