Looking for free/opensource code or description of algorithms to code (simple) and decode (hard) the 2D barcode QR code.

It doesn't seem like a trivial problem, but it's so popular in Japan that there must be something already available...

I have a colleague who worked on ZXing ("Zebra Crossing").

That's got a fair variety of platform support.
