Thomas Amberg just told me that Kaywa's QR Code solution is mentioned in the new O'Reilly book Making Things Talk. I wait for a scan of the page now;).

PS:
We were also mentioned in the german magazine acquisa, Das Magazin für Marketing und Vertrieb. Next to the article about QR Codes, the Staatstheater Darmstadt-Kaywa example is mentioned particularly. Thanks Philipp!

Also lately we were in konsumTV magazine, following up to the television report about Kaywa and QR Codes.

I am normally not that fond of incorporating logos in QR Codes, but I definitely like this one. See also the explanation of how Duncan did it.

Schüsse ins Netz. The translated title would be something like "Shots into the Web", probably coming from shooting a code. I like the way more precise and scanning* better.

And through Martin, I also discovered the TU Graz project.


* Which reminded me of Cronenberg's Scanners, a film which deeply impressed me when I was 18 and which I keep a special memory of as it was also one of my first date-movies. Watching films starting at 11 pm with a girl and then talking and doing other things;) through the night - well it was quite something at that time.
