This is actually fairly old news (although it's very cool that it just
recently got showcased on NPR) -- Taimina and Henderson wrote up their
work for the Mathematical Intelligencer back in 2001 (Vol. 23, No. 2),
and more recently similar methods (i.e., using stitch increase and
decreases for fine control of local curvature) were used to crochet
the Lorenz manifold (Osinga and Krauskopf, "Crocheting the Lorenz
Manifold", Math. Intelligencer, Vol., 26 No. 4).

In fact, crochet and knit methods are sufficiently applicable to math
(and vice versa!) that at this winter's AMS/MAA Joint Mathematics
Meetings, there was a whole session on fiber-arts and its relationship
to math, organized by sarah-marie belcastro and Carolyn
Yackel. Resources related to that session can be found at
