Microsoft Tag

Here is an interesting if only vaguely connected to Silverlight bit from Microsoft...

Microsoft 'Tag'

Personally I could do without the colors but is an interesting idea that allows these computer read tags for embedding information on a page, or email etc. Something like an ubber UPC. In silverlight I can see some uses such as on crossfader I could have a tag for each artist on the back of media tiles. but maybe only if the tags work with gray scales...
