I had installed one of the numerous QR Code extensions for Chrome (press the button and it generates a QR code of the URL to continue reading on the phone). Unfortunately, I always wanted to send the URL to my phone _after_ losing wifi contact, so the image would fail to load. I was so annoyed that I downloaded the ZXing source and learned GWT so I could compile the QREncoder to Javascript for myself. This looks like a neater and more lightweight solution.
