I came across this on Flickr and thought it was certainly worth mentioning, a cross stitched QR code. (QR codes are those square graphics that look like a funky bar code, which you can scan with your smartphone and it will take you to a website or a specific page of information.)

Then later making rounds on Facebook I noticed some more talk about QR codes being stitched and used in textile art. The geek in me is overjoyed at the concept! All this clicking and blog reading lead me to QR-3D, a site all about testing if textile versions of QR codes can work. A stitched QR code that actually scans and works, just the thought intrigues me!
QR-3D is inviting you to take part in this experiment and submit photos of finished work. You can find instructions on how to join in all the QR code stitching (or knitting, or other textile format) on this page of their site: http://qr-3d.weebly.com/take-part.html
