If you like your accessories ‘provably unique’, check out this mathematically interesting Kickstarter project – KnitYak, aka Fabienne Serriere, is going to generate some knitting patterns for scarves algorithmically, so no two scarves will be the same. They’ve hacked a knitting machine to use cellular automata to generate unique black-and-white patterns, which will be knitted in merino wool using a Jacquard (double) knit, resulting in lovely well-finished pieces by the sound of things (although the scarves start from $150, so you’d expect something pretty nice).
Check out the video below, and consider chucking some money on the KnitYak Kickstarter page.
