Hyperlinked graffiti

Interactions between the real & the virtual world are fascinating! Here's a Wired report about Grafedia, a variation on the yellow arrow theme.

If you see a graffiti somewhere which contains an underlined word written in blue, then chances are that you've encountered your first grafedia, a real world link into the virtual one. Somebody has left something @grafedia.net, and you can retrieve that content by sending email to word@grafedia.net, preferably from your mobile device.
