QR Codes in .NET

I really like the idea of QR codes. I can see so many ways of using them - they excite me ;)

This guy is knocking out a sweet little .NET library to create/encode and decode qr codes. It's open source and ready to go.

This is a nice quick and easy QR code builder that will create a code for you in the meantime and you could use runtime from a site/app you work on.
