Part 9 of Ralph Griswold's series on designing with L-Systems asks whether L-Systems created to draw plants and fractals can be reused for weave design. It proposes reinterpreting the drawing characters (F, f, +, -, brackets) as rules for building t-sequences, which are mirrored for symmetry and treadled as drawn in with twill tie-ups. An appendix gallery pairs the original L-System images with the resulting weave patterns, and the author notes there is no evident connection between image and weave.
