Nice. We have yet to test how practical it is to capture QR "ciphers" ;-) projected onto screens during presentations. They'd need to be fairly big, not just in a corner of the slide. Works OK on LCD monitors, not good on CRT monitors because of the raster lines.

A couple of updates. I like Mia Ridge's post on QR codes. 'Tinyurls you can wear' is a good description, in most of the people who I'd have to explain QR to wouldn't know what a tinyurl is either. Dan Pett at the BM also points to Google charts for creating the codes. This shows the maximum character limit varies, so the best solution would be to choose the smallest resolution possible and show it at the largest size to get round the limitations of projectors. Using Tinyurl or Is.Gd would be a way of doing that.

Thanks for the reference Alun :¬)
Might I offer a few more uses? One idea I had a while back was using a QR code as a tattoo. Being one who could never quite decide on a picture that would stay with me the rest of my life, I thought it novel to instead satisfy my nerdier tendencies and have the QR tattoo link to a private domain where I could upload any particular design I felt like, as with a desktop wallpaper. Either way, my tattoo would serve as a placeholder for years to come.
Another benefit to this could be (God forbid) I end up dead in a ditch or incapacitated and someone needed to identify me. Scanning my markings could serve an additional purpose.
Another decidedly evil use of a QR could be a virus. Much like with a shortened URL, you don't know what you're looking at until it's possibly too late. While I haven't investigated the technical side in full, in theory you could have a very simple URL - or even an actual script - written into the QR. While I'm pretty sure most phones are a little too simple to get a script to run off the bat, but I can imagine it being easier to initiate a 'hack' on a WAP/GPRS/3G phone without a Firewall than a computer with.
Just some food for thought :¬D

Hey Alun, I'm using QR codes on our new database (soon to be finished) for any page that you print off. It is another means for people to go directly to the online URL. I think it will be a while until these become more widely used, but I really like the concept. They are really easy to generate, via that google charts api. Who knows, in a couple of years, they could be everywhere. They're already on tickets, pepsi cans and various other frequently bought media. Keep being innovative. Dan
