A Chrome Packaged App that scans QR codes. Available now in Chrome Web Store!
NOTE: Seems to work well only on notebook/Chromebook computers, which have webcams that have very short-range focus by default. getUserMedia() today doesn't allow the app to specify the focus, so that means you get whatever the default is. On an iMac, this means you need a very large (over one foot wide) QR code to hold up in front of the webcam at a "normal" distance of probably 2-3 feet, which is ridiculous.
- The real brains in this app are in https://github.com/LazarSoft/jsqrcode, which is in turn a port of http://code.google.com/p/zxing. Thanks, everyone!
- The bloop-bloop sound is floating around on the web with an unclear origin.
