About 1985 I learned enough PostScript to do a little graphics stuff. I soon decided that coding in PostScript was bad for my mental health and attitude. In the meantime I did:
A hex board to produce a piece of paper upon which one could play the game of Hex. You can modify the value of n defined on line two of the program for different size boards.
A variant to make many small boards on one page in order to study small board puzzles. Number and size are parameters.
A program to tile the hyperbolic plane with pentagons. Some background here.
