QR codes in education

Is anyone interested in forming a group to try out using QR codes in the classroom? If you don't know what a QR code is, it's the thing (you see more and more in magazines and on products) that looks like this:

A smartphone with the appropriate app (I use RedLaser on my iPod) can "read" the code, which typically opens a web site or provides text or an image.

I just made the code above using this tool. Give it a try and see where it leads!
And here's a tool that creates a code that you can put on any document so if someone wants a copy of the doc, all they have to do is scan the code.
How can we use QR codes with students? Here's an article to get the ball rolling. Anyone interested?
