From the Artist:
"I wanted to break out of the basic black and white form of the QR code and try if I could somehow “hide” the code in the fabric, make it less obvious. Using more colours both in the background and in the figure itself seems to do that nicely. The only thing you have to keep in mind when using other or more colours than just black and white is to keep the contrast high enough. By the way, this is a perfect way to use leftover yarns – I didn’t have to buy any new materials for these pieces."
