Crosswords in newspapers or magazines could have some of the clues in the form of sounds like a cow mooing or a hammer pounding a nail, thunder, sneezing, etc. Just for variety. How to provide the sound to go with newspaper crosswords? I did some experiments with printed variable-width lines like the optical sound tracks on movie film, but that doesn't look promising because printed ink resolution is not nearly as good as in film. I was thinking you could drag a pen-sized reader with audio output. To evaluate whether it is even interesting to do, I've put together a test. It is not as simple as I had planned, because you need a smart phone. See the link below if you want to try the two examples. To actually do the puzzles you will need to do a screen capture and print to get a paper copy.-- flypaper, Jul 23 2014 Audio Crossword Test http://diyexperimen...udiocrosswords.htmlTwo easy crosswords with a few sound clues. [flypaper, Jul 23 2014] Have you seen Phonopaper? Google it (someone else here mentioned it). It would work fine for printing audio in newspapers.-- MaxwellBuchanan, Jul 23 2014 How about a textured print, then you could print a "rumble strip" and it would be played by dragging your pen end along it.-- pocmloc, Jul 23 2014 Thank you for info about Phonopaper. It appears to be evidence that you need a lot of paper area to hold a few seconds of sound. Maybe only a low-frequency sound if you drag a reader over a narrow width line. You would want to fit several clue lines, not too long to go along with a crossword.-- flypaper, Jul 23 2014 Re [link]: Those were interesting to solve. However, some of the audio files' filenames were the answers, and the others gave strong clues. I would have just numbered the files.-- notexactly, Jun 21 2019 random, halfbakery
