It’s a QR Code. QR stands for “Quick Response” and the image is, really, a two-dimensional bar code. You might have seen these already in other contexts, such as postage you’ve received or sent from the Post Office or products you’ve purchased from stores.
Some mobile phones have QR readers that decipher the embedded information. To download a free QR reader to your phone, go to http://reader.kaywa.com/.
Scan the image above using your mobile phone and you’ll be taken to the UoR Open Sound 2010 poll on Armacost Library’s blog. Snap, click, vote!
