Have you seen these?

They're called "QR codes" and they are popping up everywhere. I recently saw an iPhone QR code reader app, so I downloaded it and tried it on a code I saw in a magazine. What a clever idea! The code is a hyperlink to a website or a video. So, you can extend your message well beyond what is printed in the ad or-- in the case of the pineapple I bought Saturday-- the tag that was attached to the leaf.



The iPhone app also has a "creator" function. I used it to make this QR code, which is a link to this blog.
