Alas that Scott's ThumpMats calculator is no longer interactive at the above address. You can still download it and run it on your computer, but I'm a bit confused since I thought being interactive without making people download the code was the point of Gists which is why I'm not removing it from the Online category. Maybe the not interactive part will get fixed?
In any case, I've added to the top post my
Stellated Crown Knot Run List Calculator. Hopefully I've actually fixed all the bugs at this point and people find it useful.
I've been avoiding learning Javascript for half my life but if I get into it, maybe I can render the knots like Scott's Thump Mats.
