This video shows an interesting use of mobile phones in Japan. By embedding a QR code in tombstones, visitors can use their mobile phone to access additional information about the deceased. These stones are made by Ishinokoe.

What it means: mobile + physical objects can lead to interesting, think-out-of-the-box ideas. I believe we’ve only scratched the surface of future “local” innovation.

love this. An interesting evolution of this concept – as we continue to leave digital breadcrumbs connected to physical objects (e.g. Yelp Reviews of a restaurant) our descendants will be able to set their mobile devices to detect whenever they are near a place that we had a connection to – and display whatever we posted about that place. In a way it will be like we never left. Our digital ghosts will always be around saying stuff like “great pizza!” & “lousy service!”.
Do you remember the deadpages idea we had years ago!
