I just discovered this post on the Dubaiblog from Hochparterre. And I was really impressed by the similarity of Kufi and QR Codes.
In the example above I used a link to a mobile site and I imagine one could use QR Codes and Kufi's to tell the same content in different languages - once as written kufi and once as a mp3 file where someone reads the content of the kufi. This way one can address different publics.

And imagine the use in architecture, on a middle eastern telecom building full of kufi's and QR Codes.
