I have written before on the fact that since my knitting is done primarily on a Brother 910 and a Brother punchcard models, I am ever curious re and exploring ways to produce chart images that will allow me to knit patterns via mylars or punchcards, with an occasional wincrea download to my Passap via an ancient laptop. My eternal wish list to date has included the option to download to a hacked Brother model I already own, or to my Passap, directly from my Mac (presently Mavericks OS). Mathematical knits via hacked or commercial knitting machine use have been explored by some, including Claire Williams and Fabienne. With the help of online generators, even with a lack of understanding of the math involved, one can produce charts for knitting or other textile applications.
The Wolfram site is a resource for both Mac and Windows platform users who are interested in math, computation, and its visual results. There is a downloadable CDF player that allows exploration of documents and provides for download, CDF format explained, demonstrations projects, search for cellular automata. Below are some samples obtained through browsing the site. In some instances show mesh option will provide a gridded motif, show scale will indicate “stitch counts”
then there is this
