Once upon a time I tried to sell my Trianglons puzzles to magazines and
newspapers (no takers, alas) so I wrote a version of the program that
would produce the puzzles in a printable image format (with the puzzle helps
and instructions). So instead of letting all that go to waste, I thought I'd
make 15 of the puzzles available to whomever wants to print them out (and
give a little bit of puzzles for people who can't get the java to work). So
here they are - print them out and share them.
