http://youtu.be/cGTQo5IP6P0granny lives in my country,
(Republic of) Croatia, she says and proves she's been knitting QR codes all her life
there is even a word in local slang for that symbol
"šiljur"
(in english you would pronounce it like she - lure )
another thing :
Nikola Tesla was born in a village near where this granny lives,
they are joking that there must be something in those undergorund waters they all drink
She started knitting those symbols after she had a fata morgana , allegedly once, during a heavy storm,
she saw a deer that had QR codes all over his body, and since then, she always puts them in her work
her grand daughter (or daughter)
recently told her that Japanese and Americans stole her idea
