The QR-3D project is curated by UK craft scene super-boffin, Sally Fort. But what is it? QR codes are traditionally a two-dimensional image like a barcode; used by barcode readers and camera phones. They usually consist of smaller black squares on a larger square white background. The information contained within usually direct code readers to a website, but can also be used to hide text messages or other information. The project aims to help more people understand QR codes and how they can be used to share, promote, collaborate and experiment. It really does lend itself beautifully to cross-stitch, don't you think? To find out more, visit the QR-3D project website here.
