Nikolaus Gradwohl, an Austrian MAKE subscriber, created a QR code of his mother’s name that she can weave into the rugs she makes. Our very own Becky Stern was showing off her knitted QR code scarf at the Mini Maker Square at the Google I/O conference last month. She hadn’t had much luck with getting phonecams to successfully scan the code before, but a number of people at the conference were able to read it.
