Semacodes

I just read about semacodes over at KuiperCliff >. Semacodes are a really interesting technology that lets you convert a URL into an image that can be read by camera-enabled mobile phones.

There are all sorts of projects based on the technology; the most interesting of which I think is Semapedia >, which generates these things for Wikipedia > URLs that you can then affix to physical objects.

Very cool stuff.
