Seriously that is all this is... I needed something at work to read QR Codes and display them in a relatively nice way that wasn't any of the ridiculous QR Code desktop applications that currently exist on the interwebs -_-)
This was made using the ZXing library for the QR decoding which you can find over at https://github.com/zxing/zxing
And
The live webcam feed and processing is thanks to the AForge Framework over at http://www.aforgenet.com

Run it...
At the moment it supports only 2 QR Code types, URL encoded and Text encoded. I'm certain the libary includes all formats, feel free to customise to suit.
